'Master' in the Bible

God had [also] raised Rezon the son of Eliada as an adversary against him, who had fled from Hadadezer the king of Zobah, his master.

if this people go up to offer sacrifices in the house of Yahweh in Jerusalem. The heart of this people will return to their master Rehoboam the king of Judah, and they shall kill me and {return to him}."

Then the king of Israel answered and said, "As your word, my master the king; I [am] yours, and all that is mine [is yours]."
