Put the altar in front of the curtain that is before the ark of the Testimony--before the atonement cover that is over the Testimony--where I will meet with you.
Once a year Aaron shall make atonement on its horns. This annual atonement must be made with the blood of the atoning sin offering for the generations to come. It is most holy to the LORD."
"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.
Each one who crosses over to those already counted is to give a half shekel, according to the sanctuary shekel, which weighs twenty gerahs. This half shekel is an offering to the LORD.
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."
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 an offering made to the LORD by fire,
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."
