Genesis 35:15

And Jacob called the name of the place where God spake with
him, Bethel.
] He confirmed the name he had before given it, when he went to Mesopotamia, and now upon his return renews and establishes it; or he gave this name more especially to that particular spot where God conversed with him, and on which he erected a pillar, and consecrated it to religious worship, and so made it God's house, as he promised he would, ( Genesis 28:22 ) , both building an altar for sacrifice, and setting up a pillar, which was beginning an house for God.
