'Mighty' in the Bible

There have been mighty kings also over Jerusalem, who have ruled over all [the country] beyond the River; and tribute, custom, and toll, was paid to them.

and has extended loving kindness to me before the king, and his counselors, and before all the king's mighty princes. I was strengthened according to the hand of Yahweh my God on me, and I gathered together out of Israel chief men to go up with me.
