'Earnestly' in the Bible

And the Angel of the Lord [solemnly and earnestly] admonished Joshua, saying,

“When I scatter them among the nations,They will remember Me in far countries,And with their children they will live and come back [to Me and the land I gave them].

“I will pour out on the house of David and on the people of Jerusalem, the Spirit of grace (unmerited favor) and supplication. And they will look at Me whom they have pierced; and they will mourn for Him as one mourns for an only son, and they will weep bitterly over Him as one who weeps bitterly over a firstborn.
