Genesis 21:22

And it came to pass at that time
Not when Ishmael was grown up and married, but when Isaac was weaned and Ishmael was expelled:

that Abimelech, and Phichol, the chief captain of his host, spake unto
Abraham;
Abimelech was king of Gerar, the same that is spoken of in the preceding chapter, and Phichol was the general of his army; these two great personages came together and paid Abraham a visit, and had some conversation with him, who was still in Gerar, or however in some part of that country not far from it:

saying, God [is] with thee in all that thou doest;
greatly prospered him in the things of the world, for of them only could they make a judgment; they saw that he increased in worldly substance, and that his family was increased, and that he succeeded in everything in which he engaged; and, being jealous of his growing greatness and power, were desirous of securing an interest in him and in his favour.
