'Priest's' in the Bible

Whenever the chest was brought to the king's officials by the descendants of Levi, the royal secretary and the chief priest's designated officer would come, empty the chest, and take it back to its place. They did this day after day until they had collected a large amount of cash.

Then Jehoiada the priest's son Zechariah was clothed by the Spirit of God, and he stood above the people and told them, "This is what God has to say: "Why are you breaking the LORD's commandments. You'll never be successful! Because you have abandoned the LORD, he has abandoned you.'"

After the Arameans left him very sick, Joash's own servants conspired against him because Joash had murdered Jehoiada the priest's son, and they killed him on his sick bed.
