'Master of the House' in the Bible

It is enough for the disciple that he be as his teacher, and the servant as his lord. If they have called the master of the house Beelzebub, how much more shall they call them of his household?

Watch you therefore: for you know not when the Master of the house comes, at evening, or at midnight, or at the cock crowing, or in the morning:

When once the Master of the house is risen up, and has shut the door, and you begin to stand outside, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto you, I know not where you come from:

So that servant came, and showed his lord these things. Then the Master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in here the poor, and the maimed, and the lame, and the blind.
