A will
For where a testament is, there must also of necessity be the death of the testator. For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth. Whereupon neither the first testament was dedicated without blood. (Hebrews 9:16-18)
The new
For this is my blood of the new testament, which is shed for many for the remission of sins. (Matthew 26:28)
And he said unto them, This is my blood of the new testament, which is shed for many. (Mark 14:24)
Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you. (Luke 22:20)
After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. (1 Corinthians 11:25)
