Verse 7. "Slew them" - He kept the murder of Gedaliah secret, and no doubt had a band of his assassins lodged in Mizpah; and he decoyed these fourscore men thither that he might have strength to slay them. He kept ten alive because they told him they had treasures hidden in a field, which they would show him. Whether he kept his word with them is not recorded. He could do nothing good or great; and it is likely that, when he had possessed himself of those treasures, he served them as he had served their companions. Grain is preserved to the present day in subterranean pits, called mattamores, iD different parts of the east.
Verse 9. "Now the pit-was it which Asa the king had made for fear of Baasha" - See 1 Kings xv. 22. Asa made this cistern as a reservoir for water for the supply of the place; for he built and fortified Mizpah at the time that he was at war with Baasha, king of Israel.
Verse 10. "Carried away captive" - He took all these that he might sell them for slaves among the Ammonites.
Verse 14. "Went unto Johanan" - They were weary of the tyranny of Ishmael, and were glad of an opportunity to abandon him.
Verse 17. "Dwelt in the habitation of Chimham" - The estate that David gave Chimham, the son of Barzillai. See 2 Sam. xix. 37, &c. He took this merely as a resting-place; as he designed to carry all into Egypt, fearing the Chaldeans, who would endeavour to revenge the death of Gedaliah.
