'Nations' in the Bible

Woe to those who are at ease in Zion, and to those who are secure on the mountain of Samaria, the notable men of the chief of the nations, to whom the house of Israel come!

"For, behold, I will command, and I will sift the house of Israel among all the nations, as grain is sifted in a sieve, yet not the least kernel will fall on the earth.

that they may possess the remnant of Edom, and all the nations who are called by my name," says Yahweh who does this.
