'Remnant of Israel' in the Bible

When they came to Hilkiah the high priest, they delivered the money that had been brought into the house of God, which the Levites, who guarded the doors, had collected from Manasseh and Ephraim, and from all the remnant of Israel, and from all Judah and Benjamin, and the inhabitants of Jerusalem.

Now in that day the remnant of Israel, and those of the house of Jacob who have escaped, will never again rely on the one who struck them, but will truly rely on the Lord, the Holy One of Israel.

For thus says the Lord,“Sing aloud with gladness for Jacob,And shout for the first and foremost of the nations [the chosen people, Israel];Proclaim, give praise and say,‘O Lord save Your people,The remnant of Israel!’

Now it came about while I was prophesying, that Pelatiah the son of Benaiah died. Then I fell face downward and cried out loudly, “Alas, Lord God! Will You bring the remnant of Israel to a complete end?”

“I shall most certainly assemble all of you, O Jacob;I shall surely gather the remnant of Israel.I shall bring them together like sheep in the fold [multiplying the nation];Like a flock in the midst of its pasture.The place will swarm with many people and hum loudly with noise.
