'Father's' in the Bible

"Why is it that you have been searching for me?" He replied; "did you not know that it is my duty to be engaged upon my Father's business?"

For whoever shall have been ashamed of me and my teachings, of him the Son of Man will be ashamed when He comes in His own and the Father's glory and in that of the holy angels.

"But on coming to himself he said, "'How many of my father's hired men have more bread than they want, while I here am dying of hunger!

"'I entreat you then, father,' said he, 'to send him to my father's house.

And remember that I am about to send out my Father's promised gift to rest upon you. But, as for you, wait patiently in the city until you are clothed with power from on high."
