Leviticus 5:3

English Standard Version

3 or if he touches human uncleanness, of whatever sort the uncleanness may be with which one becomes unclean, and it is hidden from him, when he comes to know it, and realizes his guilt;

New International Version

3 or if they touch human uncleanness (anything that would make them unclean) even though they are unaware of it, but then they learn of it and realise their guilt;

New International Reader’s Version

3 Or suppose they touch something ‘unclean’ that comes from a human being. It could be anything that would make them ‘unclean’. Suppose they are not aware that they touched it. When they find out about it, they will be guilty.

King James Version

3 Or if he touch the uncleanness of man, whatsoever uncleanness it be that a man shall be defiled withal, and it be hid from him; when he knoweth of it , then he shall be guilty.
