Then they are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs.
(Exodus 12:7 -- NIV)

For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, ¹⁹ but with the precious blood of Christ, a lamb without blemish or defect.
(1 Peter 1:18-19 -- NIV)
