Moses
Genesis 30:43ESV·traditional attribution

Thus the man increased greatly and had large flocks, female servants and male servants, and camels and donkeys.

43. And the man increased exceedingly. Moses added this for the purpose of showing that he was not made thus suddenly rich without a miracle. We shall see hereafter how great his wealth was. For being entirely destitute, he yet gathered out of nothing, greater riches than any man of moderate wealth could do in twenty or thirty years.

Matthew Henry Presbyterian @wholebiblehenry

Here is Jacob's honest policy to make his bargain more advantageous to himself than it was likely to be. If he had not taken some course to help himself, it would have been a bad bargain indeed, which he knew Laban would never consider, or rather would be well pleased to see him a loser by, so little did Laban consult any one's interest but his own.

JACOB'S COVENANT WITH LABAN. (Gen. 30:25-43) when Rachel had born Joseph--Shortly after the birth of this son, Jacob's term of servitude expired, and feeling anxious to establish an independence for his family, he probably, from knowing that Esau was out of the way, announced his intention of returning to Canaan (Heb 13:14).
