'Nations' in the Bible

Judges, envoys, officials, Persians, the people of Erech, the Babylonians, the people of Susa (that is, the Elamites) and many other nations whom the great and honorable Osnappar deported and resettled in Samaria and in the rest of the province beyond the Euphrates River.

So the Israelis who had returned from captivity ate the Passover with all who had consecrated themselves from the uncleanness of the nations of the land in order to seek the LORD God of Israel.

because they and their sons have married foreign women. As a result, the holy people have mingled themselves among the nations of these lands. As a matter of fact, the senior officials and the rulers have been foremost in this sin."

"The land you are entering to possess is a morally unclean land due to the moral uncleanness of the nations of the lands along with their abominations that has filled it from one end to the other with their impurities. So, therefore, do not give your daughters in marriage to their sons, nor marry their daughters to your sons, and under no circumstances are you to seek their well-being or their wealth, so that you may remain strong, enjoying the best things the land has to give, and so that you may establish an inheritance for your children forever.'

should we violate your commandments by intermarrying with the nations who practice these abominations? Would you not be angry with us until you had consumed us, with not even a remnant surviving to escape?

Now confess this to the LORD God of your ancestors, and separate yourselves from the nations of the land and from foreign wives."
