Exodus 12:22

22And dip a little bundle of hyssop in the blood which is at the entrance, and sprinkle the upper threshold with it, and both of the door posts. Let none of you go out of the door of his house until morning.
12:22 Sprinkle, etc: This sprinkling the doors of the Israelites with the blood of the paschal lamb, in order to their being delivered from the sword of the destroying angel, was a lively figure of our redemption by the blood of Christ.(Challoner)
