Judges 3:16

13 And he gathered unto him the children of Ammon and Amalek, and went and smote Israel, and possessed the city of palm trees.

14 So the children of Israel served Eglon the king of Moab eighteen years.

15 But when the children of Israel cried unto the LORD, the LORD raised them up a deliverer, Ehud the son of Gera, a Benjamite, a man lefthanded: and by him the children of Israel sent a present unto Eglon the king of Moab.

16 But Ehud made him a dagger which had two edges, of a cubit length; and he did gird it under his raiment upon his right thigh.

17 And he brought the present unto Eglon king of Moab: and Eglon was a very fat man.

18 And when he had made an end to offer the present, he sent away the people that bare the present.

19 But he himself turned again from the quarries that were by Gilgal, and said, I have a secret errand unto thee, O king: who said, Keep silence. And all that stood by him went out from him.
