Then Joshua said to the people, “Sanctify yourselves [for His purpose], for tomorrow the Lord will do wonders (miracles) among you.”

And the captain of the LORD'S host said unto Joshua, Loose thy shoe from off thy foot; for the place whereon thou standest is holy. And Joshua did so.

and all the silver and gold, and vessels of brass and iron, holy they are to Jehovah; into the treasury of Jehovah they come.'

Rise up! Consecrate the people and say, ‘Consecrate yourselves for tomorrow, for thus says the Lord, the God of Israel: “There are things under the ban among you, O Israel. You cannot stand [victorious] before your enemies until you remove the things under the ban from among you.”

And Joshua said unto the people, Ye cannot serve the LORD: for he is an holy God; he is a jealous God; he will not forgive your transgressions nor your sins.

And Joshua put these words on record, writing them in the book of the law of God; and he took a great stone, and put it up there under the oak-tree which was in the holy place of the Lord.
