'King' in the Bible

And it came to pass in the fourth year of king Darius, that the word of the LORD came unto Zechariah in the fourth day of the ninth month, even in Chisleu;

Ashkelon shall see it, and fear; Gaza also shall see it, and be very sorrowful, and Ekron; for her expectation shall be ashamed; and the king shall perish from Gaza, and Ashkelon shall not be inhabited.

Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.

For I will no more pity the inhabitants of the land, saith the LORD: but, lo, I will deliver the men every one into his neighbour's hand, and into the hand of his king: and they shall smite the land, and out of their hand I will not deliver them.

And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the LORD my God shall come, and all the saints with thee.

And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.

And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.

And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.
