Leviticus 22:18-33

18Speak to Aaron and his sons and all the people of Israel and say to them, bWhen any one of the house of Israel or of the sojourners in Israel presents a burnt offering as his offering, for any of their vows or freewill offerings that they offer to the Lord, 19if it is to be accepted for you it shall be a cmale without blemish, of the bulls or the sheep or the goats. 20 dYou shall not offer anything that has a blemish, for it will not be acceptable for you. 21And when anyone eoffers a sacrifice of peace offerings to the Lord fto fulfill a vow or as a freewill offering from the herd or from the flock, to be accepted it must be perfect; there shall be no blemish in it. 22Animals gblind or disabled or mutilated or having a discharge or han itch or scabs you shall not offer to the Lord or give them to the Lord as a food ioffering on the altar. 23You may present a bull or a lamb that has a part jtoo long or too short for a freewill offering, but for a vow offering it cannot be accepted. 24Any animal that has its testicles bruised or crushed or torn or cut you shall not offer to the Lord; you shall not do it within your land, 25neither shall you offer as kthe bread of your God any such animals gotten from a foreigner. Since there is a lblemish in them, because of their mutilation, they will not be accepted for you.”

26And the Lord spoke to Moses, saying, 27 m“When an ox or sheep or goat is born, it shall remain seven days with its mother, and from the eighth day on it shall be acceptable as a food offering to the Lord. 28But you shall not kill an ox or a sheep nand her young in one day. 29And when you sacrifice a osacrifice of thanksgiving to the Lord, you shall sacrifice it so that you may be accepted. 30It shall be eaten on the same day; pyou shall leave none of it until morning: I am the Lord.

31 q“So you shall keep my commandments and do them: I am the Lord. 32 rAnd you shall not profane my holy name, that sI may be sanctified among the people of Israel. tI am the Lord who sanctifies you, 33who brought you out of the land of Egypt uto be your God: I am the Lord.”

Samuel Given to the Lord

21The man Elkanah and all his house vwent up to offer to the Lord the yearly sacrifice and to pay his vow. 22But Hannah did not go up, for she said to her husband, “As soon as the child is weaned, I will bring him, so that he may appear in the presence of the Lord wand dwell there forever.” 23 xElkanah her husband said to her, “Do what seems best to you; wait until you have weaned him; yonly, may the Lord establish his word.” So the woman remained and nursed her son until she weaned him. 24And when she had weaned him, zshe took him up with her, along with a three-year-old bull,

I will adperform my vows to you,
14that which my lips uttered
and my mouth promised aewhen I was in trouble.

with the smoke of the sacrifice of rams;
I will make an offering of bulls and goats.  Selah
