El Olam, The Everlasting God, Names Of God

Abraham, having got into a good neighbourhood, knew when he was well off, and continued a great while there. There he planted a grove for a shade to his tent, or perhaps an orchard of fruit-trees and there, though we cannot say he settled, for God would have him, while he lived, to be a stranger and a pilgrim, yet he sojourned many days, as many as would consist with his character, as Abraham the Hebrew, or passenger.

There he made, not only a constant practice, but an open profession, of his religion: There he called on the name of the Lord, the everlasting God, probably in the grove he planted, which was his oratory or house of prayer. Christ prayed in a garden, on a mountain.

Abraham kept up public worship, to which, probably, his neighbours resorted, that they might join with him. Note, Good men should not only retain their goodness wherever they go, but do all they can to propagate it, and make others good.

In calling on the Lord, we must eye him as the everlasting God, the God of the world, so some. Though God had made himself known to Abraham as his God in particular, and in covenant with him, yet he forgets not to give glory to him as the Lord of all: The everlasting God, who was, before all worlds, and will be, when time and days shall be no more. See Isaiah 40:28. - Matthew Henry
