Abraham remained a stranger and sojourner in the land. What Torah covenant?
De 5:3 The LORD made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
Abvraham is the Righteous one whom Alôhâyîm Called from the East, out of the land of the Kʰeltdî (Celtics, Chaldeans, Babylonians), and he was Called to receive an inheritance that was occupied by Goiyem.
"And I will make your seed to multiply as the stars of heaven, and will give unto your seed all these countries; and in your seed shall all the nations of the earth be blessed;
Because that Abvraham obeyed My Voice, and kept my charge, my commandments, my statutes, and my תורת (Laws)." [Genesis 26:4-5]
"As for me, behold, My Covenant is with you, and you shall be a father of many nations.
And I will make you exceeding fruitful, and I will make nations of you, and kings shall come out of you.
And I will Establish my Covenant between me and you and your seed after you in their generations for an everlasting Covenant, to be a Alôhâyîm unto you, and to your seed after you.
And I will give unto you, and to your seed after you, the land wherein you are a stranger, all the land of Canaan, for an everlasting possession; and I will be their Alôhâyîm.
And Alôhâyîm said unto Abvraham, You shall Keep My Covenant therefore, You, and your seed after you in their generations.
This is My Covenant, which you shall keep, between me and you and your seed after you; Every man child among you shall be circumcised.
And you shall circumcise the flesh of your foreskin; and it shall be a Token of The Covenant between me and you." [Genesis 17:4, & 6-11]
The Circumcision of the foreskin is a Token of The actual Covenant, when He says, "This is My Covenant..." He is referring to the real-time conversation, and open line of communication where one is able to hear His Voice, whereby if one willfully Circumcise Pride and Vanity from their Heart, they may also follow His guidance and instructions as father Abvraham did.
Abvraham is the Father of our Faith, and it is His resurrected body that shall stand in the Kingdom on the day many of the children of the kingdom shall be cast out into outer darkness.
This is The Covenant....
"Now therefore, if you will obey My Voice indeed, and keep My Covenant, then you shall be a peculiar treasure unto me above all people: for all the earth is mine:
And you shall be unto me a kingdom of priests, and an holy nation. These are the words which you shall speak unto the children of Israel." [Exodus 19:5-6]
"If you shall listen closely unto the Voice of Yéhûʷəʰ your Alôhâ, to Keep his commandments and his statutes which are (also) written in this book of the law, and if you turn unto Yéhûʷəʰ your Alôhâ with all your heart, and with all your soul.
For this commandment which I command you this day, it is not hidden from you, neither is it Far Off.
It is not in heaven, that you need to say, Who shall go up for us to heaven, and bring it unto us, that we may hear it, and do it?
Neither is it beyond the sea, that you need to say, Who shall cross over the sea for us, and bring it unto us, that we may hear it, and do it?
But the Word is very Near (Close) to you, in your Mouth, and In Your Heart, that you may do it.
See, I have set before you this day life and good, and death and evil;
In that I command you this day to love Yéhûʷəʰ your Alôhâ, to Walk in his ways, and to Keep his commandments and his statutes and his judgments, that you may live and multiply: and Yéhûʷəʰ your Alôhâ shall bless you in the land whither you are going to possess it." [Deuteronomy 30:10-16]
"And I have placed My Words in your Mouth, and I have covered you in the shadow of my hand, that I may plant the heavens, and lay the foundations of the earth, and say unto Zion, you are my people." [Isaiah 51:16]
