Charles Ellicott Commentary Genesis 35:13

"And God went up from him in the place where he spake with him." — Genesis 35:13 (ASV)

God went up from him. —This formula, used before in Genesis 17:22; Genesis 18:33, shows that this manifestation of God’s presence was more solemn than any of those previous occasions on which the Deity had revealed Himself to Jacob. It was, in fact, the acknowledgment of the patriarch as the heir of the Abrahamic covenant.
