Leviticus 5:1-4

1‘Now if a person sins after he hears a 1public 2adjuration to testify when he is a witness, whether he has seen or otherwise known, if he does not tell it, then he will bear his 3guilt.

2Or if a person touches 4any unclean thing, whether a carcass of an unclean beast or the carcass of unclean cattle or a carcass of unclean swarming things, though it is hidden from him and he is unclean, then he will be guilty.

3Or if he touches human uncleanness, of whatever sort his uncleanness may be with which he becomes unclean, and it is hidden from him, and then he comes to know it, he will be guilty.

4Or if a person 5swears thoughtlessly with his lips to do evil or to do good, in whatever matter a man may speak thoughtlessly with an oath, and it is hidden from him, and then he comes to know it, he will be guilty in one of these.
