Exodus 30:18

Moreover, he made the laver of bronze with its base of bronze, from the mirrors of the serving women who served at the doorway of the tent of meeting.

“You shall set the laver between the tent of meeting and the altar and put water in it.

He also made ten lavers of bronze, one laver held forty baths; each laver was four cubits, and on each of the ten stands was one laver.

He also made ten lavers and set five on the right side and five on the left, in which to wash things, that is, in which they would rinse things for the burnt offering; but the sea was for the priests to wash in.

Guard your steps as you go to the house of God and draw near to listen rather than to offer the sacrifice of fools; for they do not know they are doing evil.
