Midrash su Giobbe 37:7

(Deut. 32, 4) The God of truth, and without iniquity. God of truth, i.e., just as the wicked will be punished in the world hereafter even for the slightest offense which they may commit here on earth, so also are the righteous to be held to account in this world even for the slightest transgression committed; And without iniquity; i.e., just as the righteous will be rewarded in the future world even for the least meritorious act, so also are the wicked rewarded in this world even for the least meritorious act. (Ib.) Just and right in He. They [Our Rabbis] say that when a man dies and comes into the world beyond, all his deeds are laid open before him in detail, and he is told: "So and so hast thou done in that place and on that day." Whereupon he answers: "Yea," and he is told to sign his name, which he signs, as it is said (Job 37, 7) He sealeth it on the hand of every man. And not this alone, but he also acknowledges the justice of the verdict and says: "You have judged me righteously," to justify the passage (Ps. 51, 6) In order that thou mayest he righteous when thou speakest, be justified when thou judgest.

(Job 37:7:) HE SIGNS WITH EACH PERSON'S HAND. What does that mean? That when the Holy One created the human, he had all generations pass before him up until the dead would rise, the righteous and the wicked. He said to him: Look at how you have brought death upon the righteous. When Adam heard that, he began to be depressed. He said to him: Sovereign of the World, have I also done this to your world? I have no concern over the wicked, that they should die, but over the righteous, lest they murmur against me. If you please, just do not record concerning me that I brought death upon them. The Holy One said to him: Thus shall I do: When someone is going to depart from this world, the Holy One appears to him. He says to him: Write down the deeds which you have done, since you are dying for the deeds which you have done. So he writes. When he has written, he says to him: Sign; and he signs, as stated (ibid.): HE SIGNS WITH EACH PERSON'S HAND. Then, in the age to come, when the Holy One sits in judgment with his creatures, he will bring all the books of the children of Adam (mentioned in Gen. 5:1) and reveal their deeds to them. Therefore, it is stated (Job 37:7): HE SIGNS WITH EACH PERSON'S HAND….

"without wrong": When a man departs from the world, all his deeds come and present themselves to him one by one, saying: "This is what you did on this and this day. Do you believe it?" The man: "Yes, I do." The deed: "Sign!" — and he signs, viz. (Iyyov 37:7): "He makes the hand of every man sign."
