WPNT(i)
18 Therefore, not even the first covenant was inaugurated without blood;
19 because when every commandment of the Law had been proclaimed by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the scroll itself and all the people,
20 saying, “This is the blood of the covenant which God has decreed to you.”
21 Then he sprinkled both the tabernacle and all the vessels of the divine service with the blood in the same way.
