'Nations' in the Bible

Remember, I beseech thee, the word that thou commandedst thy servant Moses, saying, If ye transgress, I will scatter you abroad among the nations:

Moreover thou gavest them kingdoms and nations, and didst divide them into corners: so they possessed the land of Sihon, and the land of the king of Heshbon, and the land of Og king of Bashan.

Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved of his God, and God made him king over all Israel: nevertheless even him did outlandish women cause to sin.
