Saying, This blood is the sign of the agreement which God has made with you.

Now faith is the substance of things hoped for, and the sign that the things not seen are true.

By faith he kept the Passover, and put the sign of the blood on the houses, so that the angel of destruction might not put their oldest sons to death.

And to Jesus by whom the new agreement has been made between God and man, and to the sign of the blood which says better things than Abel's blood.
