'Knewest' in the Bible

And his lord answering said to him, Wicked and slothful bondman, thou knewest that I reap where I had not sowed, and gather from where I had not scattered;

He says to him, Out of thy mouth will I judge thee, wicked bondman: thou knewest that I am a harsh man, taking up what I have not laid down and reaping what I have not sowed.

and shall lay thee even with the ground, and thy children in thee; and shall not leave in thee a stone upon a stone: because thou knewest not the season of thy visitation.

Jesus answered and said to her, If thou knewest the gift of God, and who it is that says to thee, Give me to drink, thou wouldest have asked of him, and he would have given thee living water.
