Jeremiah 41:15

But Ishmael the son of Nethaniah escaped from Johanan with
eight men
Of the ten he brought with hin}, ( Jeremiah 41:1 ) ; two of them being slain in this skirmish, or taken by Johanan, or they fled another way: and went to the Ammonites;
who had put him upon, or however encouraged and assisted him in, his wicked attempts; though he returned to them not according to their wishes, nor with that honour and glory he thought to have done.
