And if the man be poor, thou shalt not sleep with his pledge:

Wesley's Notes

24:12 Thou shalt not sleep - But restore it before night, which intimates that he should take no such thing for pledge, without which a man cannot sleep.

Matthew Henry's Concise Commentary

24:5-13 It is of great consequence that love be kept up between husband and wife; that they carefully avoid every thing which might make them strange one to another. Man-stealing was a capital crime, which could not be settled, as other thefts, by restitution. The laws concerning leprosy must be carefully observed. Thus all who feel their consciences under guilt and wrath, must not cover it, or endeavour to shake off their convictions; but by repentance, and prayer, and humble confession, take the way to peace and pardon. Some orders are given about pledges for money lent. This teaches us to consult the comfort and subsistence of others, as much as our own advantage. Let the poor debtor sleep in his own raiment, and praise God for thy kindness to him. Poor debtors ought to feel more than commonly they do, the goodness of creditors who do not take all the advantage of the law against them, nor should this ever be looked upon as weakness.
