2 Kings 17:20 NASB

The LORD rejected all the descendants of Israel and afflicted them and gave them into the hand of plunderers, until He had cast them out of His sight.

Hosea 1:10-11 NASB

Yet the number of the sons of Israel
Will be like the sand of the sea,
Which cannot be measured or numbered;
And in the place
Where it is said to them,
"You are not My people,"
It will be said to them,
"You are the sons of the living God."
And the sons of Judah and the sons of Israel will be gathered together,
And they will appoint for themselves one leader,
And they will go up from the land,
For great will be the day of Jezreel.

Galatians 2:15-16 NASB

We are Jews by nature and not sinners from among the Gentiles; nevertheless knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified.
