1 Peter 1:18-19 NASB
knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.
Mark 15:17-20 NASB
They dressed Him up in purple, and after twisting a crown of thorns, they put it on Him; and they began to acclaim Him, “Hail, King of the Jews!” They kept beating His head with a reed, and spitting on Him, and kneeling and bowing before Him. After they had mocked Him, they took the purple robe off Him and put His own garments on Him. And they led Him out to crucify Him.
Hebrews 9:22 NASB
And according to the Law, one may almost say, all things are cleansed with blood, and without shedding of blood there is no forgiveness.
