The first-born son in every Israelite family, as well as the first-born males of their flocks and herds, belong to me. But a first-born son and every first-born donkey must be bought back from me.
However, all first-born cattle, sheep, and goats belong to me and cannot be bought back. Splatter their blood on the altar and send their fat up in smoke, so I can smell it and be pleased.
