'Knowest' in the Bible

I have proclaimed glad tidings of righteousness in the great assembly; Lo, I will not refrain my lips, O Jehovah, thou knowest.

O God, thou knowest my foolishness; And my sins are not hid from thee.

Thou knowest my reproach, and my shame, and my dishonor: Mine adversaries are all before thee.

Thou knowest my downsitting and mine uprising; Thou understandest my thought afar off.

For there is not a word in my tongue, But, lo, O Jehovah, thou knowest it altogether.
