Numbers 18:24-26

New Century Version

²⁴ but when the Israelites give a tenth of everything they make to me, I will give that tenth to the Levites as a reward. That is why I said about the Levites: ‘They will not inherit any land among the Israelites.’”

²⁵ The Lord said to Moses, ²⁶ “Speak to the Levites and tell them: ‘You will receive a tenth of everything the Israelites make, which I will give to you. But you must give a tenth of that back to the Lord.
