Exodus 30:17
Fountain of Bronze The Lord spoke to Moses and said:
You will use this ransom money given to you by the people of Israel for the upkeep of the Tent of Meeting. It will remind the Lord of the people of Israel and be the ransom for your lives.”
The rich man is not to give more, nor the poor man less, when they pay this amount for their lives.
Everyone subject to the census, that is to say, twenty years and over, must pay the sum set aside for the Lord.
Everyone subject to the census must pay the required amount of money, weighed according to the official standard, and this shall be set aside for the Lord.
“When you take a census and make a register of the people of Israel, each is to pay the Lord a ransom for his life, so that no disaster comes on them when the census is being made.
Once a year, Aaron is to perform the atonement on the horns of this altar; he shall do this atonement with the blood of the victim to take away sins. And you shall do the same once a year in future generations. This ceremony will be extremely holy in the eyes of the Lord.”
You must not offer unholy incense on this altar, or animal or grain offering, or pour out any wine offering.
and in the evening twilight, when Aaron puts the lamps back, he must burn it again. You must make these offerings of incense before the Lord unfailingly from generation to generation.
