10 Once a year Aaron must purify the altar by smearing on its four corners the blood of an animal sacrificed for sin, and this practice must always be followed. The altar is sacred because it is dedicated to me.
11 The Lord said to Moses:
12 Find out how many grown men there are in Israel and require each of them to pay me to keep him safe from danger while you are counting them.
13-15 Each man over nineteen, whether rich or poor, must pay me the same amount of money, weighed according to the official standards.
16 This money is to be used for the upkeep of the sacred tent, and because of it, I will never forget my people.
17 The Lord said to Moses:
18-21 Make a large bronze bowl and a bronze stand for it. Then put them between the altar for sacrifice and the sacred tent, so the priests can wash their hands and feet before entering the tent or offering a sacrifice on the altar. Each priest in every generation must wash himself in this way, or else he will die there.
