'Diligently' in the Bible

“Why then do You not pardon my transgressionAnd take away my sin and guilt?For now I will lie down in the dust;And You will seek me [diligently], but I will not be.”

“If you would [diligently] seek GodAnd implore the compassion and favor of the Almighty,

“Listen diligently to my speech,And let my declaration fill your ears.

“Listen carefully to my speech,And let this be the consolation.

“Behold, as wild donkeys in the desert,The poor go to their work, diligently seeking food;As bread for their children in the desert.
