Joshua 5:10-15 (Holy Saturday Vespers)
While the people of Israel were encamped in Gilgal they kept the passover on the fourteenth day of the month at evening in the plains of Jericho. And on the morrow after the passover, on that very day, they ate of the produce of the land, unleavened cakes and parched grain. And the manna ceased on the morrow, when they ate of the produce of the land; and the people of Israel had manna no more, but ate of the fruit of the land of Canaan that year. When Joshua was by Jericho, he lifted up his eyes and looked, and behold, a man stood before him with his drawn sword in his hand; and Joshua went to him and said to him, "Are you for us, or for our adversaries?" And he said, "No; but as commander of the army of the LORD I have now come." And Joshua fell on his face to the earth, and worshiped, and said to him, "What does my lord bid his servant?" And the commander of the LORD's army said to Joshua, "Put off your shoes from your feet; for the place where you stand is holy." And Joshua did so.
