Matthew Poole and continuators on Jeremiah 41:17

17 And they departed, and dwelt in the habitation of Chimham, which is by Bethlehem, to go to enter into Egypt .

When Iohanan had (as was before expressed) recovered the Jews whom Ishmael had carried away as Prisoners, he came and dwelt with them in the habitation of Chimham, concerning this Chimham all that we read in Scripture is, 2 Sam. 19.37, 38, 40. he was the son of Barzillai, whom David would have had to have gone along with him to his Court, but he being 80 years old excused himself, and desired that his son Chimham might be accepted in his stead, v. 38. David agreeth it, and promiseth him, and promised to do for him, whatsoever his Father should desire on his behalf, possibly David having an estate near thereabouts might give a portion of it to him, which though it returned to the Family of David in the year of Jubilee, yet from Chimham's House there, might retain the name of the habitation of Chimham, into those parts Iohanan retired with a further design to go into Egypt.
