'Labor' in the Bible

their descendants who remained in the land after them, those the Israelites had not completely destroyed—Solomon imposed forced labor on them; it is this way today.

Then King Rehoboam sent Hadoram, who was in charge of the forced labor, but the Israelites stoned him to death. However, King Rehoboam managed to get into his chariot to flee to Jerusalem.

But as for you, be strong and let not your hands be weak, for there is reward for your labor."

Then the king and Jehoiada gave it to those in charge of the labor on the Lord’s temple, who were hiring stonecutters and carpenters to renovate the Lord’s temple, also blacksmiths and coppersmiths to repair the Lord’s temple.

As a result, the workmen did their labor, and the repair work progressed steadily under their supervision, and they restored God's Temple back to what it should be, and strengthened it, too.
