¹⁹He shall sprinkle some of the blood on it with his finger seven times, and cleanse it, and make it holy from the uncleanness of the children of Israel.

¹⁸The rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed, and the priest shall make atonement for him before the LORD.

²⁴then I will also walk contrary to you; and I will strike you, even I, seven times for your sins.

¹⁸“‘If you in spite of these things will not listen to me, then I will chastise you seven times more for your sins.

²⁸then I will walk contrary to you in wrath. I will also chastise you seven times for your sins.

⁸It was so, that when Joshua had spoken to the people, the seven priests bearing the seven trumpets of rams’ horns before the LORD advanced and blew the trumpets, and the ark of the LORD’s covenant followed them.

⁴Seven priests shall bear seven trumpets of rams’ horns before the ark. On the seventh day, you shall march around the city seven times, and the priests shall blow the trumpets.

¹⁴He shall take some of the blood of the bull, and sprinkle it with his finger on the mercy seat on the east; and before the mercy seat he shall sprinkle some of the blood with his finger seven times.

⁹The sons of Aaron presented the blood to him; and he dipped his finger in the blood, and put it on the horns of the altar, and poured out the blood at the base of the altar;

¹⁵He killed it; and Moses took the blood, and put it around on the horns of the altar with his finger, and purified the altar, and poured out the blood at the base of the altar, and sanctified it, to make atonement for it.
