HUH?
ISRAEL DIDN'T EXIST AT THAT TIME.
GOD SAID THAT TO ABRAM whom He brought out of Ur.
and the reference of blessings for all the nations of the earth was Jesus.
I REALIZE THE TWO FOLLOWING CHAPTERS MEAN ONE ACTUALLY HAS TO READ, BUT IF YOU ARE WILLING TO READ THEM, YOU COULD SETTLE THE MATTER ONCE AND FOR ALL.
Galatians 3
The Law and the Promise
15To give a human example, brothers:
f even with a man-made covenant, no one annuls it or adds to it once it has been ratified.
16
Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ.
17This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void.
18For if the inheritance comes by the law, it no longer comes by promise; but God gave it to Abraham by a promise.
19Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made, and it was put in place through angels by an intermediary.
20Now an intermediary implies more than one, but God is one.
21Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law.
22But the Scripture imprisoned everything under sin, so that the promise by faith in Jesus Christ might be given to those who believe.
23Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed.
24So then, the law was our guardian until Christ came, in order that we might be justified by faith.
25But now that faith has come, we are no longer under a guardian,
26for in Christ Jesus you are all sons of God, through faith.
27For as many of you as were baptized into Christ have put on Christ.
28There is neither Jew nor Greek, there is neither slave
g nor free, there is no male and female, for you are all one in Christ Jesus.
29And if you are Christ’s, then you are Abraham’s offspring, heirs according to promise.
Galatians 4
Example of Hagar and Sarah
21Tell me, you who desire to be under the law, do you not listen to the law?
22For it is written that Abraham had two sons, one by a slave woman and one by a free woman.
23But the son of the slave was born according to the flesh, while the son of the free woman was born through promise.
24Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar.
25Now Hagar is Mount Sinai in Arabia;e she corresponds to the present Jerusalem, for she is in slavery with her children. 26But the Jerusalem above is free, and she is our mother. 27For it is written,
“Rejoice, O barren one who does not bear;
break forth and cry aloud, you who are not in labor!
For the children of the desolate one will be more
than those of the one who has a husband.”
28Now you,f brothers, like Isaac, are children of promise. [remember Abraham? above?] 29But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now.
30But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.”
31So, brothers, we are not children of the slave but of the free woman.
