'Knoweth' in the Bible

All things have been delivered unto me of my Father: and no one knoweth who the Son is, save the Father; and who the Father is, save the Son, and he to whomsoever the Son willeth to reveal him .

For all these things do the nations of the world seek after: but your Father knoweth that ye have need of these things.

the lord of that servant shall come in a day when he expecteth not, and in an hour when he knoweth not, and shall cut him asunder, and appoint his portion with the unfaithful.

And he said unto them, Ye are they that justify yourselves in the sight of men; but God knoweth your hearts: for that which is exalted among men is an abomination in the sight of God.
