When Jacob runs away from Esau he goes to his uncle at Padam Aram.On his way he passes through the city of Luz and and has a dream at night of angels ascending and descending,God also gives him promises of the land.When he wakes up in the morning he takes a pillar,anoints it and calls the place Bethel
Genesis 28:11-19 NKJV
11 So he came to a certain place and stayed there all night, because the sun had set. And he took one of the stones of that place and put it at his head, and he lay down in that place to sleep. 13 And behold, the Lord stood above it and said: “I am the Lord God of Abraham your father and the God of Isaac; the land on which you lie I will give to you and your descendants 19 And he called the name of that place [d]Bethel; but the name of that city had been Luz previously
Some years later when he returns from Padan Aram he passes through the same place.God appears to him at night again and gives him the same promises he had given earlier on.In the morning when he wakes up he takes a pillar ,anoints it and calls the place Bethel
Genesis 35:6-15 NKJV
6 So Jacob came to Luz (that is, Bethel), which is in the land of Canaan, he and all the people who were with him9 Then God appeared to Jacob again, when he came from Padan Aram, and blessed him. 13 Then God went[d] up from him in the place where He talked with him. 14 So Jacob set up a pillar in the place where He talked with him, a pillar of stone; and he poured a drink offering on it, and he poured oil on it. 15 And Jacob called the name of the place where God spoke with him, Bethel.
Why does Jacob name the place twice?
