'Nations' in the Bible

There were 150 Jews and officials, as well as guests from the surrounding nations at my table.

In it was written:It is reported among the nations—and Geshem agrees—that you and the Jews plan to rebel. This is the reason you are building the wall. According to these reports, you are to become their king

When all our enemies heard this, all the surrounding nations were intimidated and lost their confidence, for they realized that this task had been accomplished by our God.

Didn’t King Solomon of Israel sin in matters like this? There was not a king like him among many nations. He was loved by his God and God made him king over all Israel, yet foreign women drew him into sin.
