He was pierced for our transgressions...

Old Testament prophecies of the Crucifixion

Isaiah 53:3-12

He was despised and rejected by men; a man of sorrows, and acquainted with grief; and as one from whom men hide their faces he was despised, and we esteemed him not. Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted. But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed. All we like sheep have gone astray; we have turned—every one—to his own way; and the Lord has laid on him the iniquity of us all.

He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is silent, so he opened not his mouth. By oppression and judgment he was taken away; and as for his generation, who considered that he was cut off out of the land of the living, stricken for the transgression of my people? And they made his grave with the wicked and with a rich man in his death, although he had done no violence, and there was no deceit in his mouth.

Yet it was the will of the Lord to crush him; he has put him to grief; when his soul makes an offering for guilt, he shall see his offspring; he shall prolong his days; the will of the Lord shall prosper in his hand. Out of the anguish of his soul he shall see and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous, and he shall bear their iniquities. Therefore I will divide him a portion with the many, and he shall divide the spoil with the strong, because he poured out his soul to death and was numbered with the transgressors; yet he bore the sin of many, and makes intercession for the transgressors.

Isaiah 52:13-15
Behold, my servant shall act wisely; he shall be high and lifted up, and shall be exalted. As many were astonished at you—his appearance was so marred, beyond human semblance, and his form beyond that of the children of mankind—so shall he sprinkle many nations; kings shall shut their mouths because of him; for that which has not been told them they see, and that which they have not heard they understand.

Psalm 22 (selected verses)
1: "My God, My God, why have You forsaken Me?" 

6: despised of the people.

8: He trusted in the Lord, let Him rescue Him; let Him deliver Him, since He delights in Him!"
13: They gape at Me with their mouths, like a raging and roaring lion.
14: I am poured out like water, and all My bones are out of joint; my heart is like wax; it has melted within Me.

Deuteronomy 21:22-23
And if a man has committed a crime punishable by death and he is put to death, and you hang him on a tree, his body shall not remain all night on the tree, but you shall bury him the same day, for a hanged man is cursed by God.You shall not defile your land that the Lord your God is giving you for an inheritance.

Numbers 21:8-9
And the Lord said to Moses, “Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live.” So Moses made a bronze serpent and set it on a pole. And if a serpent bit anyone, he would look at the bronze serpent and live.

Genesis 3:15
"I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.”
