'Diligently' in the Bible

Then he sent them to Bethlehem, saying, “Go and search carefully for the Child; and when you have found Him, report to me, so that I too may come and worship Him.”

Then Herod, when he realized that he had been tricked by the magi, was extremely angry, and he sent [soldiers] and put to death all the male children in Bethlehem and in all that area who were two years old and under, according to the date which he had learned from the magi.

For the [pagan] Gentiles eagerly seek all these things; [but do not worry,] for your heavenly Father knows that you need them.
