'Diligently' in the Bible

Let it be known to the king that we went to the house of the great God in the province of Judah. It is being built with cut stones, and its beams are being set in the walls. This work is being done diligently and succeeding through the people’s efforts.

May the God who caused His name to dwell there overthrow any king or people who dares to harm or interfere with this house of God in Jerusalem. I, Darius, have issued the decree. Let it be carried out diligently.

Then Tattenai governor of the region west of the Euphrates River, Shethar-bozenai, and their colleagues diligently carried out what King Darius had decreed.

Whatever is commanded by the God of heaven must be done diligently for the house of the God of heaven, so that wrath will not fall on the realm of the king and his sons.
