When the Jews offered sacrifices, God had something to say about what happened to the blood of the sacrifices. Eight times in Leviticus, we read where God expected the priests (or Moses) to put blood on the horns of the altar, and then the rest of the blood was to be poured “at the bottom of the altar” (Lev. 4:7, 18, 25, 30, 34, 5:9, 8:15, 9:9).
