"And Kore the son of Imnah the Levite, the porter at the east [gate], was over the freewill-offerings of God, to distribute the oblations of Jehovah, and the most holy things." — 2 Chronicles 31:14 (ASV)

And Kore the son of Imnah the Levite, the porter towards the
east
At the east gate of the temple; see (1 Chronicles 26:17)

was over the freewill offerings of God, to distribute the oblations of
the Lord ;
to the priests and Levites, for whose use they were; or to deliver out the fine flour, oil, and wine, and frankincense, for the meat and drink offerings:

and the most holy things ;
which belonged to the priests only to eat of, as the remainder of the meat offerings, the sin and trespass offerings, and the shewbread.
