Numbers 15:25-26

25Then the priest will make things right with God for all the Israelites. The Lord will forgive them. That is because their sin was a mistake. They have brought their offering, an offering by fire to the Lord. And they have brought their sin offering to the Lord, for their mistake.

26God will forgive all the Israelites and the foreign people who live among you. That is because your sin was a mistake. And also you offered the proper sacrifices to me.
