'Rulers' in the Bible

And to Shemaiah his son were sons born, who were rulers in their father's house; for they were mighty men of valour.

and his brethren, men of valour, two thousand seven hundred chief fathers, whom king David made rulers over the Reubenites and the Gadites and the half tribe of the Manassites, for every matter pertaining to God, and the affairs of the king.
