John Gill Commentary Genesis 31:39

"That which was torn of beasts I brought not unto thee; I bare the loss of it; of my hand didst thou require it, whether stolen by day or stolen by night." — Genesis 31:39 (ASV)

That which was torn [of beasts] I brought not to you To show what had befallen it; that so it might appear he had one the less to account for to him.

I bore the loss of it He took it upon himself, as if it had been somewhat blameworthy in him, as the word used signifies; and so made satisfaction for it;

which, how he did, when he had no wages, is difficult to say: he might have some perquisites allowed him by Laban, though he had no settled salary; or he might lay himself under obligation to make it good whenever it was in his power, as follows.

of mine hand did you require it, [whether] stolen by day, or stolen by night Whether by men or beasts; or by men in the daytime, and by beasts in the night, as the Targums of Jonathan and Jerusalem distinguish:

Laban was so rigorous and unjust as to require the restoration of them, or an equivalent for them at the hand of Jacob; all which were contrary to the law of God, (Exodus 22:10–13).
