Hi,

There are THREE distinct and separate covenants spoken of  :  the "Abrahamic Covenant ", the "New Covenant of My blood",  and the "New Covenant for the Jews" during the Great Tribulation.

THE ABRAHAMIC COVENANT FOR THE JEWS AND THE WORLD :

The Abrahamic  Covenant contained  THREE promises : a  promised land for the Jews, a promised nation for the Jews, and a promised blessing for ALL THE FAMILIES, ie. NATIONS of Gentiles , of the earth according to :

Genesis 12:3

"...and in thee shall ALL THE FAMILIES of the earth be blessed."   Jesus "confirmed",  ie. fulfilled, this THIRD promise of the Abrahamic Covenant  according to :

Daniel 9:25, 26 & 27 ( read all three as one Scripture for context )

"And He (  Messiah ) shall CONFIRM ( ie, fulfill ) THE COVENANT WITH MANY ( ie. confirm the THIRD promise of the Abrahamic Covenant which is a  Messiah for ALL THE FAMILIES of the world )"

Romans 15:8  “Now I say that Jesus Christ was a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers:”

THE NEW COVENANT OF BLOOD FOR ALL THE WORLD:

During His Olivet Discourse, the evening before His crucifixion, Jesus made a NEW COVENANT OF HIS BLOOD which blessed  ALL THE FAMlIES OF NATIONS of the earth according to : 

Matthew 26:28

"For this is My blood of THE NEW TESTAMENT , ie. NEW COVENANT, which is shed FOR MANY for the remission of sins."

A NEW COVENANT FOR THE JEWS ONLY:

AFTER the resurrection/rapture of His Body of Christ Church , during the Great Tribulation BEFORE the Second Coming of the Lord , God will make a  NEW COVENANT for the left-behind Jews which are the 1/3 of the surviving Jews from the Gog-magog War according to :

Zechariah 13:8-9

"And it shall come to pass that in all the land ( of Israel ) , saith the Lord, TWO PARTS therein shall be cut-off and DIE,  but THE THIRD shall be left therein. And I will  bring the THIRD PART through the fire ( Gog-Magog War ) ,  and I will refine them as silver is refined, and I will try them as gold is tried."

Hebrews 8:10

"For this is THE COVENANT that I will make with the House of Israel , AFTER THOSE DAYS,  ( of the Gog-Magog War ) saith the Lord , I will put My laws into their mind and write them in  their hearts  , and I will be to them their God and they  shall be to Me My people."

SO, THERE YOU HAVE IT :

Three separate and distinct covenants.

Blessings to you...
