'Remnant' in the Bible

Thus saith Jehovah of hosts: If it be marvellous in the eyes of the remnant of this people in those days, should it also be marvellous in mine eyes? saith Jehovah of hosts.

But now I will not be unto the remnant of this people as in the former days, saith Jehovah of hosts.

For there shall be the seed of peace; the vine shall give its fruit, and the ground shall give its increase, and the heavens shall give their dew; and I will cause the remnant of this people to inherit all these things.

And I will take away his blood out of his mouth, and his abominations from between his teeth; and he also shall be a remnant for our God; and he shall be as a chieftain in Judah, and Ekron as a Jebusite.
