But by becoming a curse for us Christ has redeemed us from the curse that the Law brings; for the scripture says, “Anyone who is hanged on a tree is under God's curse.”
it is not to remain there overnight. It must be buried the same day, because a dead body hanging on a post brings God's curse on the land. Bury the body, so that you will not defile the land that the Lord your God is giving you.
Christ himself carried our sins in his body to the cross, so that we might die to sin and live for righteousness. It is by his wounds that you have been healed.
