'Son' in the Bible

The words of Amos, who was one of the sheep breeders from Tekoa—what he saw regarding Israel in the days of Uzziah, king of Judah, and Jeroboam son of Jehoash, king of Israel, two years before the earthquake.

So Amos answered Amaziah, “I was not a prophet or the son of a prophet; rather, I was a herdsman, and I took care of sycamore figs.

I will turn your feasts into mourningand all your songs into lamentation;I will cause everyone to wear sackclothand every head to be shaved.I will make that grieflike mourning for an only sonand its outcome like a bitter day.
