'Humbleth' in the Bible

Seest thou how Ahab humbleth himself before me? because he humbleth himself before me, I will not bring the evil in his days: but in his son's days will I bring the evil upon his house.

He croucheth, and humbleth himself, that the poor may fall by his strong ones.

Who humbleth himself to behold the things that are in heaven, and in the earth!

And the mean man boweth down, and the great man humbleth himself: therefore forgive them not.
