It comes from God's word. Read and mark your Bible. Lamb implies recipient of punishment. The Lord has laid on Him the iniquity of us all. He took our punishment on the cross as our substitute. Abraham sacrificing Isaac is a picture of this.
Isaiah 53:
Surely he hath borne our griefs, and carried our sorrows; yet we did esteem him stricken,smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed. All we like sheep have gone astray; we have turned every one to his own way; and
the LORD hath laid on him the iniquity of us all.
He was oppressed, yet when he was afflicted he opened not his mouth; as a lamb that is led to the slaughter, and as a sheep that before its shearers is dumb, so he opened not his mouth. By oppression and judgment he was taken away; and as for his generation, who among them considered that he was cut off out of the land of the living for the transgression of my people to whom the stroke was due? And they made his grave with the wicked, and with a rich man in his death; although he had done no violence, neither was any deceit in his mouth.
Yet it pleased the LORD to bruise him; He hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by the knowledge of himself shall my righteous servant justify many; and he shall bear their iniquities. Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he poured out his soul unto death, and was numbered with the transgressors: yet he bare the sin of many, and made intercession for the transgressors.

[SUP]7 [/SUP]But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
[SUP]8 [/SUP]Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
