'Unsearchable' in the Bible

Who does great and unsearchable things,Marvelous things without number.

“Behold, God is exalted, and we do not know Him;The number of His years is unsearchable.

“Tell us [Job] what words [of man] shall we say to such a Being;We cannot state our case because of darkness [that is, our ignorance in the presence of the unsearchable God].

They devise acts of injustice, saying,“We are ready with a well-conceived plan.”For the inward thought and the heart of a man are deep (mysterious, unsearchable).

Great is the Lord, and highly to be praised,And His greatness is [so vast and profound as to be] unsearchable [incomprehensible to man].

As the heavens for height and the earth for depth,So the hearts and minds of kings are unsearchable.

Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are His judgments and decisions and how unfathomable and untraceable are His ways!
