Judges 3:14-20

And the Israelites served Eglon king of Moab eighteen years. But when the Israelites cried out to the LORD [for help], the LORD raised up a man to rescue them, Ehud the son of Gera, a Benjamite, a left-handed man. And the Israelites sent a gift of tribute by him to Eglon king of Moab. Now Ehud made for himself a sword a cubit long, which had two edges, and he bound it on his right thigh under his robe. And he brought the tribute to Eglon king of Moab. Now Eglon was a very fat man. And when Ehud had finished presenting the tribute, he sent away the people who had carried it. But Ehud himself turned back from the sculptured stones at Gilgal, [and he returned to Eglon] and said [to him], “I have a secret message for you, O king.” Eglon said “Keep silence.” And all who attended him left him. Ehud came to him as he was sitting alone in his [private] cool upper chamber, and Ehud said, “I have a message from God for you.” And the king got up from his seat.
