We're getting to an important part of the instructions: the credibility of witnesses.
This section is key for the jury as they weigh whether the prosecution's star witness, Michael Cohen - a convicted felon who went to prison in part for lying to Congress - has succeeded in appearing credible.
Justice Merchan reminds jurors that if they find just one part of a testimony untruthful, they may disregard the whole testimony of that witness. Or they may just disregard the part of the testimony they find untruthful.
Here are some of the other questions the judge says they must consider:
Did the witness have an opportunity to see or hear the
events about which they testified?
Did the witness have the ability to recall those events
accurately?
The jury is paying close attention
Kayla Epstein
Reporting from court
The jury is listening carefully as Justice Merchan re-reads his detailed instructions.
One juror has a large notepad, another seems to be writing down every word. A few are simply turned toward Justice Merchan, absorbing what he says.
This case is a complex one, and the jury's desire to re-hear the instructions indicates that they want to make sure they understand how they must weigh the evidence and testimony.
A reminder that jurors are not allowed to have the instructions with them in the deliberation room, nor do they have access to previous testimony transcripts, only evidence from the case.

Donald Trump is looking particularly disengaged as half of the jury instructions are read again to the court.
He sits in his chair with his eyes closed.
His lawyers Todd Blanche and Emil Bove sit on either side of him and look toward the judge as he tells the jury once again about “limiting instructions”.
Trump’s son Eric and lawyer Alina Habba are also watching the judge from the row behind Trump.
The complex questions from the jury
Kayla Epstein
Reporting from court
The jury has asked for a broad
range of the instructions to be read back.
These pages include general
instructions about evidence, making inferences from the evidence, the burden of
proof in a criminal trial, and what constitutes reasonable doubt.
It also includes limiting
instructions about certain evidence in this case - for example, that newspaper
articles are in evidence only to mark that they exist, not for their contents.
The instructions also
cover the testimony of Michael Cohen, and how the jury is allowed to weigh his
credibility and his involvement in the actions central to this case.
Most importantly, Justice
Merchan will re-read his instructions about the crimes that Trump has been
charged with.

They ask for instructions. He begins to read pages six through to 35. This is expected to take about half an hour.

The jury has asked to hear some of Justice Juan Merchan's instructions again - which he first read to them on Wednesday morning.
In a nutshell – these instructions are when a judge explains to the jury how to interpret the law and evidence while they’re deciding on their verdict.
Justice Merchan's instructions told them about the relevant laws that should guide their deliberations and help keep them on track.
“Jury instructions should ideally be brief, concise, non-repetitive, relevant to the case’s details, understandable to the average juror,” according to Cornell Law School.
A judge’s instructions – perhaps because of an error or lack of clarity – have been used to launch successful appeals in the past.
For this reason, Justice Merchan will have carefully thought about what and how he instructed the jury.
Jury returns to the courtroom
Kayla Epstein
Reporting from court
As usual, the 12 New Yorkers walk straight past Donald Trump without looking at him.
Sometimes 90% of journalism is just hanging around - and that is nowhere more true than when it comes to court cases.
Now that the jury is out, everyone is asking one question: when do you think the verdict will come?
It is, of course, both a highly pertinent and completely pointless question.
Juries can and should take whatever time they need to come to their conclusions - it's not a race, there are no prizes here for being the fastest or the slowest, and, most importantly, they could be dealing with someone's liberty and reputation.
Nevertheless, the prediction industry is in full flow: what did it mean when juror X scratched her ear; or when juror Y avoided Donald Trump's gaze. One fellow traveller even suggested to me that jurors could string it out a bit because that way they would get a couple of days of free lunches.
In truth, the jury room is, and ought to be, a bit of a mystery - as long as sausages come out at the end, you don't necessarily want to see how they're being made.
Got questions?
Donald Trump's hush-money trial has been a complicated affair.
So naturally people have a lot of questions.
If you are wondering about any particular issue related to this case, you can send your queries to YourQuestions@bbc.co.uk.
Please include your name, age and location with any question you send in.
And later today we will have some of our US experts answer them.
Trump arrives in court

Prior to Donald Trump entering the courtroom, he spoke to the media.
Trump repeated many accusations he has made before, calling the case a "disgrace".
"Everyone's against this case," Trump said, calling it "rigged".
He read out quotes from commentators, legal analysts and supporters that have recently appeared in the media criticising the case, a common theme for Trump's statements in the last few weeks.
He also complained about the gag order put in place by Justice Juan Merchan, whom Trump called "very conflicted".
"I'm gagged so I can't talk as much as I would like to about this ridiculous case," Trump said.
He then walked into court without taking any questions.
Yesterday, Trump raised eyebrows when he claimed after leaving court that "Mother Theresa could not beat these charges".

Donald Trump is back in court, wearing a sky-blue tie today.
His entourage is somewhat smaller, with his second-eldest son, Eric Trump, as the main guest.
Before sitting at the defence table, Trump walks back to where Eric is sitting and they have a chat.
It's impossible to hear what they're saying, but Trump casts a couple glances at the press - he knows we're watching closely.

Good morning from the media overflow room
Madeline Halpert
Reporting from court
As Kayla mentioned, we will begin today with the re-reading of some key testimony from the trial.
The jury wants to hear four pieces of testimony in particular, and half of them are about an important meeting that witnesses say took place in 2015.
Both former tabloid publisher David Pecker and Michael Cohen, Trump's former fixer, told the court that they had a meeting in Trump Tower in August of that year with Donald Trump.
It was during that meeting that Pecker and Cohen say they concocted a "catch-and-kill" scheme to buy and bury negative stories about Trump as he ran for president in 2016. These stories included Trump's alleged sexual encounters with other women.
The jury has requested both Pecker and Cohen's testimony about this meeting.
Some see this as a good sign for prosecutors that jurors are wanting to revisit this key event. But jury questions during deliberations are common, and it's too soon to tell exactly what it means.
A reminder of what this trial is all about

Donald Trump has been charged with business fraud over hush-money payments to ex-porn actress Stormy Daniels.
Daniels claims she and Trump had sex, and that she accepted $130,000(£104,500) from his former lawyer before the 2016 election in exchange for her silence about the encounter.
Prosecutors allege Trump had his personal lawyer, Michael Cohen, make the payments, and then they claim Trump fraudulently recorded the transaction in his company’s books as legal expenses when in fact he was paying Cohen back for the hush-money payments.
Paying hush-money is not illegal, but the prosecution alleges how the payment was recorded amounts to election fraud.
Since the allegations surfaced in 2018, the former president has denied any sexual involvement with Daniels.
He's facing 34 counts of fraud, and has pleaded not guilty to all of them. Trump also denies having sex with Stormy Daniels.
Day two of the waiting game
Kayla Epstein
Reporting from court
Good morning from day two of jury deliberations in Donald Trump’s criminal trial. It’s all a waiting game from here on in, though the hours have already been punctuated with a bit of excitement.
Yesterday, late in the afternoon, the jury sent two notes to the judge. They asked for portions of testimony from witnesses David Pecker, the ex-publisher of the National Enquirer tabloid, and Michael Cohen, Trump’s former fixer.
The jury also asked the judge to reread portions of his instructions to them.
This morning, Justice Merchan will begin by addressing those questions. The requested testimony - an estimated 30 pages - will be read back to the jurors. The judge will then repeat some, or all, of his instructions.
This could take up a good portion of the morning. Then, the jury will be sent back into the deliberation room to continue weighing the evidence.
Today may bring more questions - or a verdict. Until then, we wait.
Welcome back
Hello, and thanks for joining our live coverage.
We’re back for day two of jury deliberations, with court set
to begin in New York around 09:30 (14:30 BST) today.
It’s likely we’ll start the morning with a reading of transcripts
from earlier in the trial, after jurors sent a note to Justice Juan Merchan late
yesterday asking for more information about some of the evidence that was
presented over the past few weeks.
Stay with us as we bring you the latest from court.

In total, they want the judge to re-read from page 7 to 35 of his instructions, which should take about 30 minutes to read.
They have also requested headphones that work with the laptop they've been issued to review evidence.
Justice Merchan suggests to the court that they should also get speakers.
