Genesis 35:7

And he builded there an altar, and named that place, To God, who made His Shekinah to dwell in Bethel, because there had been revealed to him the angels of the Lord, in his flight from before Esau his brother.

ויקרא למקום, which was outside Luz, where he had erected a monument 34 years earlier when he was on his way from his home El Bet El.

Originally, he had called the town known as Luz merely Bet El. Now he named the site where he had had the dream with the ladder El Bet El. This site was outside the town previously known as Luz. He added the word El, seeing that during all the intervening years G’d had stood by him.

ויקרא למקום, to this inn for wayfarers where he had spent the night on his way from home some 34 years ago when the Torah had referred to it as ויפגע במקום (28,11)

א-ל בית א-ל, “the sanctuary of Bet El.”

ויבן שם מזבח, this means that he built the altar in the house he had built there at the site of the original monument of which he had said in 28,22 “this will become a house of G’d.” We explained this on that verse. It does not matter that the house itself was not mentioned here separately.

ויקרא למקום א-ל בית א-ל. He had already called it Bet El on a previous occasion, Now he only expanded the name. Compare our commentary on 33,20.

כי שם נגלו אליו האלוקים, a reference to the angels ascending and descending the ladder whom he had seen in his dream. Alternatively, the meaning of the word ה-אלוקים is a reference to G’d, Himself, not an intermediary. The reason why he used the plural mode נגלו instead of נגלה when the subject is only G’d Himself, is that this is a form of great respect and honour for the subject [known as pluralis majestatis when a king refers to himself in the plural. Ed.] compare Psalms 149,2 ישמח ישראל בעושיו, “Let Israel rejoice in its Maker.” A similar construction is found in Job 35,10 איה אלו-ה עושי?, “Where is the Lord, My Maker?” There are more such examples in Scripture.
