Romans 9:27

Isaiah 10:20-23 NIV
In that day the remnant of Israel, the survivors of Jacob, will no longer rely on him who struck them down but will truly rely on the Lord, the Holy One of Israel. A remnant will return, a remnant of Jacob will return to the Mighty God. Though your people be like the sand by the sea, Israel, only a remnant will return. Destruction has been decreed, overwhelming and righteous. The Lord, the Lord Almighty, will carry out the destruction decreed upon the whole land.
