Surely He took on our infirmities and carried our sorrows;
yet we considered Him stricken by God, struck down and afflicted.
But He was pierced for our transgressions, He was crushed for our iniquities;
the punishment that brought us peaceH7965 was upon Him, and by His stripes we are healed.
We all like sheep have gone astray, each one has turned to his own way;
and the LORD has laid upon Him the iniquity of us all.
Isaiah 53:4-6
The Tony Evans Study Bible has a good note for this passage:
53:5-6 These verses couldn’t more clearly depict what Jesus Christ endured. The use of language is precise regarding the kind of death he would die (he was pierced) and the reason for it (because of our iniquities) (53:5). He was punished . . . for the iniquity of us all. Hundreds of years before it would happen, the prophet testified to the substitutionary atonement of Christ on the cross. (35)
