Saul, the first king of God's people, a tyrant to train the king of God's favor, David. David, his throne established forever. . . Solomon, the wise foolish king. Daniel, who knew the Real King in spite of the malicious king of his imprisonment. The Old Testament follows those who reign to the end with the final king, Jehoiachin, captured monarch of Judah, the end of Hebrew kings but not of Gentile ones.
Kings are central and peripheral.
Kings of earth's thrones, named, remembered. Then there is a radical change . . . The New Testament is strangely indifferent to earthly thrones and kings of nations. Herod merely mentioned, having no power to kill the Holy Infant he feared. King Agrippa, noted only as he relates to Paul's story.
