In Genesis 30:43, Jacob's flocks multiplied greatly under Laban — those same increased herds now supply the generous gift listed here.

In Genesis 31:9, Jacob says God took Laban's livestock and gave it to him — that God-given wealth is what he's sending to Esau here.

In Genesis 31:16, Rachel and Leah affirm God took their father's wealth for them — the same riches now being used as gifts here.
