'Son' in the Bible

The words of Amos, who was among the sheep breeders of Tekoa, which he spoke concerning Israel during the reign of Uzziah, king of Judah and during the reign of Joash's son Jeroboam, king of Israel, two years before the earthquake.

Amos replied in answer to Amaziah, "I am no prophet, nor am I a prophet's son, for I have been shepherding and picking the fruit of sycamore trees.

I will turn your festivals into mourning, and all of your songs to dirges. I will cause all of you to put on sackcloth and to shave all of your heads. I will make that time like mourning for an only son, and its conclusion will be like the end of a bitter day."
