Genesis 21:33 - Joseph Benson’s Commentary on the Old and New Testaments

And Abraham 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. And called there on the name of the Lord Probably in the grove he planted, which was his oratory, or house of prayer: he kept up public worship, in which, probably, some of his neighbours joined with him. Men should not only retain their goodness wherever they go, but do all they can to propagate it, and make others good. The everlasting God Though God had made himself known to Abraham as his God in particular, 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.
