And Kore, the son of Imnah the Levite, the keeper of the east door, had control of the offerings freely given to God, and the distribution of the offerings of the Lord and the most holy things.

And his captains freely gave an offering to the people, the priests, and the Levites. Hilkiah and Zechariah and Jehiel, the rulers of the house of God, gave to the priests for the Passover offerings two thousand, six hundred small cattle and three hundred oxen.
