So Jacob came to Luz, which is in the land of Canaan, that is, Bethel, he and all the people that were with him.

Jamieson-Fausset-Brown Bible Commentary

6. So Jacob came to Luz . that is, Beth-el-It is probable that this place was unoccupied ground when Jacob first went to it; and that after that period [Calvin], the Canaanites built a town, to which they gave the name of Luz [Ge 28:19], from the profusion of almond trees that grew around. The name of Beth-el, which would, of course, be confined to Jacob and his family, did not supersede the original one, till long after. It is now identified with the modern Beitin and lies on the western slope of the mountain on which Abraham built his altar (Ge 12:8).

Matthew Henry's Concise Commentary

35:6-15 The comfort the saints have in holy ordinances, is not so much from Beth-el, the house of God, as from El-beth-el, the God of the house. The ordinances are empty things, if we do not meet with God in them. There Jacob buried Deborah, Rebekah's nurse. She died much lamented. Old servants in a family, that have in their time been faithful and useful, ought to be respected. God appeared to Jacob. He renewed the covenant with him. I am God Almighty, God all-sufficient, able to make good the promise in due time, and to support thee and provide for thee in the mean time. Two things are promised; that he should be the father of a great nation, and that he should be the master of a good land. These two promises had a spiritual signification, which Jacob had some notion of, though not so clear and distinct as we now have. Christ is the promised Seed, and heaven is the promised land; the former is the foundation, and the latter the top-stone, of all God's favours.
