Ehud was the son of Gera, of the tribe of Benjamin. Once the Israelites were in the Promised Land, they began disobeying God again. So God sent Eglon, the king of Moab to rule over them. Uniting his bands with those of the Ammonites and the Amalekites, he crossed the Jordan and took the city of Jericho, holding the whole district in subjugation for eighteen years.
When the Israelties prayed to God to deliver them, he gave them a left handed man named Ehud. The Israelites sent him with tribute to Eglon king of Moab.
Now Ehud had made a double-edged sword about a foot and a half long, which he strapped to his right thigh under his clothing. He presented the tribute to Eglon king of Moab, who was a very fat man. After Ehud had presented the tribute, he sent on their way the men who had carried it. At the idols near Gilgal he himself turned back and said, "I have a secret message for you, O king."
The king had his attendants leave. Ehud then humbly approached the throne and whispering, "This is the message from God," he plunged the sword into the king's stomach. Calmly, he left the room, locking the doors behind him. By the time the servants discovered their master was dead, Ehud had made good his escape.
He called the Israelites to arms and they routed the Moabites at the fords of the Jordan, putting 10,000 of them to death.
