'Diligence' in the Bible

but we ourselves will go with diligence armed before the children of Israel, until we have brought them to their place; and our little ones shall dwell in the strong cities because of the inhabitants of the land.

Be it known to the king that we went into the province of Judah, to the house of the great God, which is being built with great stones, and timber is laid in the walls, and this work is being carried on with diligence, and prospers in their hand.
