Charles Spurgeon Commentary Genesis 33:3-4

"And he himself passed over before them, and bowed himself to the ground seven times, until he came near to his brother. And Esau ran to meet him, and embraced him, and fell on his neck, and kissed him: and they wept." — Genesis 33:3-4 (ASV)

God had been very gracious to him, and all his fears were gone, so he met Esau as a brother, not as an enemy, and the four hundred men were willing to become his protectors.
