2 Tawarikh 4:6

4:6 He made ten washing basins; he put five on the south side and five on the north side. In them they rinsed the items used for burnt sacrifices; the priests washed in “The Sea.”

Yehezkiel 42:13

42:13 Then he said to me, “The north chambers and the south chambers which face the courtyard are holy chambers where the priests ¹  who approach the Lord will eat the most holy offerings. There they will place the most holy offerings – the grain offering, the sin offering, and the guilt offering, because the place is holy.

[42:13]  ¹ sn The priests are from the Zadokite family (Ezek 40:6; 44:15).
