Matteo 2:8

Herod carried out his scheme: And he sent them to Bethlehem and said. Go and search diligently for the young Child; and when ye have found Him, bring me word again.

Eager for the success of his plans, he nevertheless manages to make his guileless visitors feel that he has nothing but the favorable outcome of their quest at heart. The text implies the idea of great haste. He sent them off at once with the urgent entreaty, almost command: Go and search. Leave nothing undone, make your search most thorough, in order that the Child may be found. And not only that:

That I may come and worship Him also.

He crowns his hypocrisy with a final base lie. For it was not that he wanted to bow down to the Child in adoring worship, but he intended to bow down the Child's soul into the dust of death.
