Moses brought to the Israelites very specific commands from God on how they were to offer sacrifices. “And the LORD called unto Moses, and spake unto him out of the tabernacle of the congregation, saying, Speak unto the children of Israel, and say unto them, If any man of you bring an offering unto the LORD, ye shall bring your offering of the cattle, even of the herd, and of the flock. If his offering be a burnt sacrifice of the herd, let him offer a male without blemish: he shall offer it of his own voluntary will at the door of the tabernacle of the congregation before the LORD.” (Leviticus 1:1-3) The instructions continued on with many different types of sacrifices that they were to offer. That included burnt offerings, meat offerings, peace offerings, and sin offerings. Even if they sacrificed exactly as God commanded, there were limits to their benefits. “For it is not possible that the blood of bulls and of goats should take away sins.” (Hebrews 10:4) Only our Savior Jesus could be that perfect sacrifice that has power to save us from our sins.
