'Sin' in the Bible

They offered at the dedication of this house of God 100 bulls, 200 rams, 400 lambs, and, as a sin offering for all Israel, 12 male goats, according to the number of Israel’s tribes.

Also the [former] exiles who had come from the captivity offered burnt offerings to the God of Israel: 12 bulls for all Israel, 96 rams, 77 lambs, and 12 male goats for a sin offering. All this was a burnt offering to the Lord.
