Exodus 30:17 NIV: Then the LORD said to Moses,

Exodus 30:16 Receive the atonement money from the Israelites and use it for the service of the tent of meeting. It will be a memorial for the Israelites before the LORD, making atonement for your lives."

Exodus 30:18 "Make a bronze basin, with its bronze stand, for washing. Place it between the tent of meeting and the altar, and put water in it.

2 Chronicles 4:6 He then made ten basins for washing and placed five on the south side and five on the north. In them the things to be used for the burnt offerings were rinsed, but the Sea was to be used by the priests for washing.
