'Knowest' in the Bible

Thou knowest that I am not wicked; and there is none that can deliver out of thine hand.

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

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

Should it be according to thy mind? he will recompense it, whether thou refuse, or whether thou choose; and not I: therefore speak what thou knowest.

Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?

Hast thou perceived the breadth of the earth? declare if thou knowest it all.

Knowest thou it, because thou wast then born? or because the number of thy days is great?

Knowest thou the ordinances of heaven? canst thou set 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?
