Hi, Chopper,
It was just a figure of speech, but not without scriptural support. Recall that Israel had multiplied its numbers to be "as the sand of the sea:"
"For though thy people Israel be as the sand of the sea, yet a remnant of them shall return:. . ." (Isa 10:22)
But the promise had not been fulfilled. The nations outside Israel were not blessed. Nor was Israel after they broke the covenant time after time.
Then Jesus received the promise of the Covenant:
"Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ." (Galatians 3:16)
"Of this man's seed hath God according to his promise raised unto Israel a Saviour, Jesus:" (Acts 13:23)
"Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear." (Acts 2:33)
And through Him are all nations blessed, beginning with Israel:
"Unto you first [, Israel,] God, having raised up his Son Jesus, sent him to bless you, in turning away every one of you from his iniquities." (Acts 3:26)
"That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith" (Gal 3:14)
"And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise." (Galatians 3:29)
Christ was also the author of the Covenant:
"All things were made by him; and without him was not any thing made that was made." (John 1:3)
It was just a figure of speech--a metaphor. I was implying Israel finally "crucified" the covenant, as they "tried to do" from almost the beginning (i.e., my reference to Moses;) but they did not "kill" it.
