'King' in the Bible

The word of the LORD which came unto Zephaniah the son of Cushi, the son of Gedaliah, the son of Amariah, the son of Hizkiah, in the days of Josiah the son of Amon, king of Judah.

I will remove those who worship the stars in the sky from their rooftops, those who swear allegiance to the Lord while taking oaths in the name of their 'king,'

And it hath come to pass, In the day of the sacrifice of Jehovah, That I have laid a charge on the heads, And on sons of the king, And on all putting on strange clothing.

The LORD hath taken away thy judgments, he hath cast out thine enemy: the king of Israel, even the LORD, is in the midst of thee: thou shalt not see evil any more.
