'Known' in the Bible

And he said, Who made thee a prince and a judge over us? Thinkest thou to kill me, as thou killedst the Egyptian? And Moses feared, and said, Surely the thing is known.

and I appeared unto Abraham, unto Isaac, and unto Jacob, as God Almighty; but by my name Jehovah I was not known to them.

Or if it be known that the ox was wont to gore in time past, and its owner hath not kept it in, he shall surely pay ox for ox, and the dead beast'shall be his own.

For wherein now shall it be known that I have found favor in thy sight, I and thy people? is it not in that thou goest with us, so that we are separated, I and thy people, from all the people that are upon the face of the earth?
