“You must not offer the blood of my sacrifice with yeast; the sacrifice from the feast of Passover must not remain until the following morning. ¹

So Moses took the blood and splashed it on ¹  the people and said, “This is the blood of the covenant ²  that the Lord has made with you in accordance with all these words.”
