'Earnestly' in the Bible

Just as it is written in the Law of Moses, all this tragedy has come on us. Yet we have not wholeheartedly begged for forgiveness and sought the favor of the Lord our God by turning from our wickedness and paying attention to and placing value in Your truth.

O the blessedness of him who is waiting earnestly, and doth come to the days, a thousand, three hundred, thirty and five.
