'Accursed' in the Bible

But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.

As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.

For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

Christ has purchased our freedom from the curse of the Law by becoming accursed for us--because "Cursed is every one who is hanged upon a tree."
