'Taskmaster' in the Bible

Then King Rehoboam sent Adoram, who was in charge of the forced labor [to represent him], and all Israel stoned him to death. And King Rehoboam quickly mounted his chariot to escape to Jerusalem.

The prisoners together are at ease; they hear not the voice of the taskmaster.

“He scorns the tumult of the city,And does not hear the shouting of the taskmaster.

"Instead of bronze, I'll bring gold, and instead of iron, I'll bring silver; instead of wood, bronze, and instead of stones, iron. I'll appoint peace as your supervisor and righteousness as your taskmaster.
