'Knowest' in the Bible

Lo, I will bring a nation upon you from far, O house of Israel, saith the LORD: it is a mighty nation, it is an ancient nation, a nation whose language thou knowest not, neither understandest what they say.

A watch-tower I have given thee, Among My people a fortress, And thou knowest, and hast tried their way.

But thou, O LORD, knowest me: thou hast seen me, and tried mine heart toward thee: pull them out like sheep for the slaughter, and prepare them for the day of slaughter.

And I will make thee to pass with thine enemies into a land which thou knowest not: for a fire is kindled in mine anger, which shall burn upon you.

O LORD, thou knowest: remember me, and visit me, and revenge me of my persecutors; take me not away in thy longsuffering: know that for thy sake I have suffered rebuke.

And thou, even thyself, shalt discontinue from thine heritage that I gave thee; and I will cause thee to serve thine enemies in the land which thou knowest not: for ye have kindled a fire in mine anger, which shall burn for ever.

As for me, I have not hastened from being a pastor to follow thee: neither have I desired the woeful day; thou knowest: that which came out of my lips was right before thee.

Yet, LORD, thou knowest all their counsel against me to slay me: forgive not their iniquity, neither blot out their sin from thy sight, but let them be overthrown before thee; deal thus with them in the time of thine anger.

Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.
