'Known' in the Bible

and the sin wherewith they have sinned against it have become known; then the congregation shall present a young bullock for the sin-offering, and shall bring it before the tent of meeting;

And if any one sin, and hear the voice of adjuration, and he is a witness whether he hath seen or known it, if he do not give information, then he shall bear his iniquity.

And if any one sin and do against any of all the commandments of Jehovah what should not be done, and hath not known it, yet is he guilty, and shall bear his iniquity.
