'Ruler' in the Bible

When a man shall take hold of his brother in the house of his father,'saying , Thou hast clothing, be thou our ruler, and let this ruin be under thy hand;

in that day shall he lift up his voice , saying, I will not be a healer; for in my house is neither bread nor clothing: ye shall not make me ruler of the people.

Send ye the lambs for the ruler of the land from Selah to the wilderness, unto the mount of the daughter of Zion.
