'Knowest' in the Bible

Although thou knowest that I am not wicked, And there is none that can deliver out of thy hand?

What knowest thou, that we know not? What understandest thou, which is not in us?

Knowest thou not this of old time, Since man was placed upon earth,

Shall his recompense be as thou wilt, that thou refusest it? For thou must choose, and not I: Therefore speak what thou knowest.

Who determined the measures thereof, if thou knowest? Or who stretched the line upon it?

Hast thou comprehended the earth in its breadth? Declare, if thou knowest it all.

Doubtless , thou knowest, for thou wast then born, And the number of thy days is great!

Knowest thou the ordinances of the heavens? Canst thou establish the dominion thereof in the earth?

Knowest thou the time when the wild goats of the rock bring forth? Or canst thou mark when the hinds do calve?

Canst thou number the months that they fulfil? Or knowest thou the time when they bring forth?
