Genesis 26:28

And they said, we saw certainly that the Lord was with thee,.... Not only while he was among them, by the fruitfulness of the land he sowed, by the increase of his family, his flocks and herds, but also since he was gone from them, in the valley of Gerar, and now in Beersheba:

and we said; one to another, assembled in privy council, in which this affair was talked over and debated:

let there now be an oath betwixt us, [even] betwixt us and thee: what was between us and thy father, or between thine ancestors and ours, let it be renewed and confirmed before us; so Onkelos and Jarchi; see

Genesis 21:23:

and let us make a covenant with thee; the articles of which follow.
