'Competent' in the Bible

King David appointed Jerijah, his relatives, and 2,700 competent men who were each family heads, to oversee the tribes of Reuben and Gad, and the half-tribe of Manasseh regarding everything pertaining to God as well as matters relating to the king.

Stay away from a foolish man, for you will not find competent advice.

young men without blemish and handsome in appearance, skillful in all wisdom, endowed with intelligence and discernment, and quick to understand, competent to stand [in the presence of the king] and able to serve in the king’s palace. He also ordered Ashpenaz to teach them the literature and language of the Chaldeans.
