'King' in the Bible

For this Melchizedek, king of Salem, priest of God Most High, who met Abraham returning from the slaughter of the kings and blessed him,

to whom also Abraham divided a tenth part of all (being first, by interpretation, king of righteousness, and then also king of Salem, which is king of peace;

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