'Master' in the Bible

those who say, "By our tongues we will prevail; our lips belong to us. Who is master over us?"

I told the LORD, "You are my master, I have nothing good apart from you."

He made him the master over his household, the manager of all his possessions

Consider this: as the eyes of a servant focus on what his master provides, and as the eyes of a female servant focus on what her mistress provides, so our eyes focus on the LORD our God, until he has mercy on us.
