Atonement Money

11 Then the LORD said to Moses,
12 “When you take a census of the Israelites to count them, each one must pay the LORD a ransom for his life at the time he is counted. Then no plague will come on them when you number them.
13 Each one who crosses over to those already counted is to give a half shekel,a according to the sanctuary shekel, which weighs twenty gerahs. This half shekel is an offering to the LORD.
14 All who cross over, those twenty years old or more, are to give an offering to the LORD.
15 The rich are not to give more than a half shekel and the poor are not to give less when you make the offering to the LORD to atone for your lives.
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.”

Basin for Washing

17 Then the LORD said to Moses,
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.
19 Aaron and his sons are to wash their hands and feet with water from it.
20 Whenever they enter the tent of meeting, they shall wash with water so that they will not die. Also, when they approach the altar to minister by presenting a food offering to the LORD,
21 they shall wash their hands and feet so that they will not die. This is to be a lasting ordinance for Aaron and his descendants for the generations to come.”
