'Knoweth' in the Bible

Even a stork in the heavens knoweth her appointed times, and the turtle-dove and the swallow and the crane observe the time of their coming; but my people know not the judgment of Jehovah.

but let him that glorieth glory in this, that he understandeth and knoweth me, that I am Jehovah, who exercise loving-kindness, judgment, and righteousness in the earth; for in these things I delight, saith Jehovah.

because they have committed infamy in Israel, and have committed adultery with their neighbours' wives, and have spoken words of falsehood in my name, which I had not commanded them: and I am he that knoweth, and am witness, saith Jehovah.
