Then Nehemiah the governor, Ezra the priestly scribe, and the Levites who were imparting understanding to the people said to all of them, “This day is holy to the lord your God. Do not mourn or weep.” For all the people had been weeping when they heard the words of the law.
“You are to put the Urim and the Thummim into the breastpiece of decision; and they are to be over Aaron’s heart when he goes in before the Lord. Aaron is to bear the decisions of the Israelites over his heart before the Lord continually.
And he will stand before Eleazar the priest, who will seek counsel for him before the Lord by the decision of the Urim. At his command they will go out, and at his command they will come in, he and all the Israelites with him, the whole community.”
Of Levi he said: Your Thummim and Urim belong to your godly one, whose authority you challenged at Massah, and with whom you argued at the waters of Meribah.
