12  That thou shalt set apart unto the Lord all that openeth the matrix, and every ^bfirstling that cometh of a beast which thou hast; the males shall be the Lord's.

  17  But the ^afirstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire, for a sweet savour unto the Lord.

  3  And they also took of the firstlings of their flocks, that they might offer sacrifice and burnt offerings according to the law of Moses;

  19  And in process of time it came to pass that Cain brought of the ^afruit of the ground an offering unto the Lord.

  12  And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat ^aoffering that remaineth of the offerings of the Lord made by fire, and eat it without leaven beside the altar: for it is most holy:

  62  And the king, and all Israel with him, ^aoffered sacrifice before the Lord.
