'Ever' in the Bible

Look upon Zion, the city of our appointed feasts and observances;Your eyes will see Jerusalem, a undisturbed settlement,A tent which will not be taken down;Not one of its stakes will ever be pulled up,Nor any of its ropes be severed.

The burning will not be quenched night or day;Its smoke will go up forever.From generation to generation it will lie in ruins;No one will ever again pass through it.

Beware that Hezekiah does not mislead you by saying, “The Lord will rescue us.” Has any one of the gods of the nations [ever] rescued his land from the hand of the king of Assyria?
