'Ruler' in the Bible

and Joseph is the ruler over the land, he who is selling to all the people of the land, and Joseph's brethren come and bow themselves to him -- face to the earth.

and now, ye -- ye have not sent me hither, but God, and He doth set me for a father to Pharaoh, and for lord to all his house, and ruler over all the land of Egypt.

and they declare to him, saying, 'Joseph is yet alive,' and that he is ruler over all the land of Egypt; and his heart ceaseth, for he hath not given credence to them.
