Ann ... point understood that you are trying to make.
Notwithstanding, the noun for "Covenant" isn't there in that scripture. Jesus didn't use that word in this instance even though he had just previouosly used in when describing THE New Covenant (Testament) just nine verses earlier:
20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Strongs 1242.
diatheke, dee-ath-ay'-kay; from 1303; properly, a disposition, i.e. (specially) a contract (especially a devisory will):--covenant, testament.
The context is critical here: The disciples were concerned about what they were going to get out of this, they wondered who was greatest. They had paid a heavy price in being disfellowshipped from much of their families and now Jesus was going away. They were a little rattled.
So, like a good sheperd he comforted them by reminding them that they would be given a kingdom just as he had been given one and that they would all be together again.
"Ye are they which have continued with me in my temptations. And I appoint unto you a kingdom, as my Father hath appointed unto me; That ye may eat and drink at my table"
1303.
diatithemai, dee-at-ith'-em-ahee; middle voice from 1223 and 5087; to put apart, i.e. (figuratively) dispose (by assignment, compact, or bequest):--appoint, make, testator.
Jesus gives, assigns, or appoints a kingdom to his followers. Even if a person allowed for the clumsy "make a covenant" rendering, there is not two covenants here. There is only one for the forgiveness of sins at that dinner table.
Mt. 26: 27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
Clearly Fred Franz used this occasion to use the exact same English word for a different Greek word for the sole purpose of obscuring just exacly what THE New Covenant was.
He acheived his purpose. Millions of people now reject their only hope of passing judgement because they were LIED to about what is the New Covenant. When people are lied to they will do anything. The Japanese would have never surrendered in WWII because they were LIED TO and told that the Americans were cannibals and would eat them and their families.
Furthermore, that clumsy translation in the NWT and the subsequent theology built upon it are lies straight from the pits of Hell.
