Moses
Genesis 33:5ESV·traditional attribution

And when Esau lifted up his eyes and saw the women and children, he said, “Who are these with you?” Jacob said, “The children whom God has graciously given your servant.”

5. And he lifted up his eyes. Moses relates the conversation held between the brothers. And as Esau had testified his fraternal affection by tears and embraces, there is no doubt that he inquires after the children in a spirit of congratulation.

Matthew Henry Presbyterian @wholebiblehenry

We have here the discourse between the two brothers at their meeting, which is very free and friendly, without the least intimation of the old quarrel. It was the best way to say nothing of it. They converse, I. About Jacob's retinue, Gen 33:5-7. Eleven or twelve little ones, the eldest of them no fourteen years old, followed Jacob closely: Who are these? says Esau.

And he lift up his eyes, and saw the women and children,.... After the salutation had passed between him and his brother Jacob, he looked, and saw behind him women and children, Jacob's two wives and his two handmaids, and twelve children he had by them: and said, who are those with thee? who do those women and children belong to that follow thee?
