2 Samuel 19:38

And the king answered, Chimham shall go over with me,.... He admitted of him instead of his father:

and I will do unto him that which shall seem good unto thee; he puts it to Barzillai, and leaves it with him to ask what he would for his son, and he would grant it. We nowhere read what it was that Barzillai asked, or whether he asked anything; only this we read, that some hundreds of years afterward there was a place called the habitation of Chimham near Bethlehem, Jeremiah 41:17; which makes it probable that David gave him a paternal estate of his there, since Bethlehem was his city; and the Targum on that place is expressly for it;

Jeremiah 41:17:

and whatsoever thou shalt require of me, [that] will I do for thee; whatever suit he should make to him, or whatever favour he should ask of him hereafter, when returned to his own city, he would grant it to him, if it could be possibly done; such a sense should he always retain of his kindness to him.
