Then Ishmael took captive...
10Then Ishmael took captive all the remnant of the people who were in Mizpah, the king’s daughters and all the people who were left in Mizpah, whom Nebuzaradan the captain of the bodyguard had put in the custody of Gedaliah the son of Ahikam. Ishmael the son of Nethaniah took them captive and proceeded to cross over to the sons of Ammon.
