Who was the Biblical king of Judea?

Judea was the Greek and Latin form of ‘Judah’.

According to the Bible, Saul was the first King over Judea that was chosen by the people. However, God rejected Saul and anointed David as King, and interesting enough when David did come into power Judah was the first to recognize it. 2 Samuel 2:4 And the men of Judah came, and there they anointed David king over the house of Judah.

The true King of Judah, however, is none less that Jesus Christ. The town of Bethlehem was located in Judah and the true ruler of Israel was prophesied to come from this town… Micah 5:2 But thou, Bethlehem, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.

The fulfillment of that prophecy happened when Christ was born: Matthew 2:5-6 And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet, And thou Bethlehem, in the land of Juda, art not the least among the princes of Juda: for out of thee shall come a Governor, that shall rule my people Israel.

One of the Lord’s Titles is the Lion of the Tribe of Judah: Revelation 5:5 And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.

Good Question, I hope this answered it for you!
