'King' in the Bible

For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;

To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;

By faith Moses, having been born, was hid three months by his parents, because they saw the child comely, and were not afraid of the decree of the king;

By faith he forsook Egypt, not fearing the wrath of the king: for he endured, as seeing him who is invisible.
