'Known' in the Bible

He said, "Who made you a prince and a judge over us? Do you plan to kill me, as you killed the Egyptian?" Moses was afraid, and said, "Surely this thing is known."

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

Or if it is known that the bull was in the habit of goring in the past, and its owner has not kept it in, he shall surely pay bull for bull, and the dead animal shall be his own.
