Judges 3:14-18

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

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.

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.

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

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