The Lord said to Moses,
"When you take a census of the people of Israel, each man is to pay me a price for his life, so that no disaster will come on him while the census is being taken.
Everyone included in the census must pay the required amount of money, weighed according to the official standard. Everyone must pay this as an offering to me. 1
References for Exodus 30:13
Everyone being counted in the census, that is, every man twenty years old or older, is to pay me this amount.
The rich man is not to pay more, nor the poor man less, when they pay this amount for their lives.
Collect this money from the people of Israel and spend it for the upkeep of the Tent of my presence. This tax will be the payment for their lives, and I will remember to protect them."
