'Perish' in the Bible

Ashkelon shall see it, and fear; Gazah also, and she shall be greatly pained; Ekron also, for her expectation shall be put to shame: and the king shall perish from Gazah, and Ashkelon shall not be inhabited.

And I said, I will not feed you: that which dieth, let it die; and that which perisheth let it perish; and let them which are left eat every one the flesh of another.

For behold, I will raise up a shepherd in the land, who shall not visit those that are about to perish, neither shall seek that which is strayed away, nor heal that which is wounded, nor feed that which is sound; but he will eat the flesh of the fat, and tear their hoofs in pieces.
