So, Do it means that Herod think himself as Christ?
The newborn king is now equated with the Christ. “Messiah” and “King of the Jews” doubtless coalesced in the minds of many. Herod reveals his superficial knowledge of Scripture by having to ask the religious authorities where this Messiah is to be born
- I don’t think Blomberg says this here
- Herod was a king of the Jews, but he was not the "King of the Jews" as a proper noun. He was nervous merely because he heard that there is another king besides himself. There's nothing related to his sense of identity regarding "Christ" (or "Messiah") here.
- I don't think he saw himself as the Messiah but simply wanted to preserve his position of power. If he did think it at all the response as to where the Messiah was born would have immediately demolished any such hope as he had not been born in Bethlehem.
