The vine that became the nation of Israel after the covenant with Moses has been cast off and is ready to be burned. That seed has been sown again with men and beast to be grafted back into the true vine once again. The vine of the Church that was in the wilderness, before they turned their backs to follow Moses instead.
Acts 7:37-39
This is that Moses, which said unto the children of Israel, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear. This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and with our fathers:who received the lively oracles to give unto us:
To whom our fathers would not obey, but thrust him from them, and in their hearts turned back again into Egypt.
Romans 11:19-27
Thou wilt say then, The branches were broken off, that I might be grafted in. Well;
because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: For if God spared not the natural branches, take heed lest he also spare not thee. Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness,
if thou continue in his goodness: otherwise thou also shalt be cut off. And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graff them in again. For if thou wert cut out of the olive tree which is wild by nature, and wert grafted contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be grafted into their own olive tree?
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this is my covenant unto them, when I shall take away their sins.
They are cut off because of unbelief, they are only grafted back in through Faith.
Jeremiah 31:27-30
Behold, the days come, saith the Lord,
that I will sow the house of Israel and the house of Judah
with the seed of man, and with the seed of beast.
And it shall come to pass, that like as I have watched over them,
to pluck up, and to break down, and to throw down,
and to destroy, and to afflict;
so will I watch over them, to build, and to plant, saith the Lord.
In those days they shall say no more,
The fathers have eaten a sour grape,
and the children's teeth are set on edge.
But every one shall die for his own iniquity:
every man that eateth the sour grape,
his teeth shall be set on edge.
Jeremiah 31:31-34
Behold, the days come, saith the Lord,
that I will make a new covenant
with the house of Israel, and with the house of Judah:
Not according to the covenant that I made with their fathers
in the day that I took them by the hand
to bring them out of the land of Egypt;
which my covenant they brake,
although I was an husband unto them, saith the Lord:
But this shall be the covenant that I will make with the house of Israel;
After those days, saith the Lord,
I will put my law in their inward parts,
and write it in their hearts;
and will be their God,
and they shall be my people.
And they shall teach no more every man his neighbour, and every man his brother, saying,
Know the Lord: for they shall all know me,
from the least of them unto the greatest of them, saith the Lord:
for I will forgive their iniquity,
and I will remember their sin no more.
Micah 4:1-2
But in the last days it shall come to pass,
that the mountain of the house of the Lord shall be established in the top of the mountains,
and it shall be exalted above the hills;
and people shall flow unto it.
And many nations shall come, and say,
Come, and let us go up to the mountain of the Lord,
and to the house of the God of Jacob;
and he will teach us of his ways,
and we will walk in his paths:
for the law shall go forth of Zion,
and the word of the Lord from Jerusalem.
