When Ehud departed, Eglon’s servants came. And when they saw that the doors of the upper room were locked, they said, “He is only relieving himself in the cool room.”

When the apostles returned, they told Him all that they had done. He took them with Him and He privately withdrew [across the Jordan] to a city called Bethsaida.
