'Son' in the Bible

The words of Amos, who was among the shepherds from Tekoa, which he saw concerning Israel in the days of Uzziah the king of Judah and in the days of Jeroboam the son of Jehoash, two years {before} the earthquake.

And Amos answered and said to Amaziah, "I am not a prophet and I [am] not a son of a prophet, but I [am] a herdsman and I am one taking care of sycamore trees.
