Joshua 5:13-14

When Joshua was near Jericho, he looked up and saw standing in front of him a man holding a drawn sword. Joshua approached him and said, “Are you on our side or on our enemies’?” “Neither,” he replied. “I have not come to take sides but to take charge. I am the Commander of YAHWEH’s armies.” At once, Joshua threw himself facedown to the ground and worshiped, and he said to him, “I will do whatever you command, my Lord.”
