'Testament' in the Bible

Take of it, all of you, for this is my blood of the testament, which is given for men for the forgiveness of sins.

And he said to them, This is my blood of the testament, which is given for men.

And in the same way, after the meal, he took the cup, saying, This cup is the new testament, made with my blood which is given for you.

In the same way, with the cup, after the meal, he said, This cup is the new testament in my blood: do this, whenever you take it, in memory of me.

Because where there is a testament, there has to be the death of the man who made it.

For a testament has effect after death; for what power has it while the man who made it is living?
