Leviticus 5:3 Meaning and Commentary

Leviticus 5:3

Or if he touch the uncleanness of man
The dead body of a man, or the bone of a dead body, or a grave, or any profluvious or menstruous person:

whatsoever uncleanness [it be] that a man shall be defiled withal:
not morally, but ceremonially:

and it be hid from him;
he is not sensible that he has touched any thing ceremonially unclean:

when he knoweth [of it], then he shall be guilty:
acknowledge his guilt, and offer a sacrifice for it, as after directed.

Leviticus 5:3 In-Context

1 If you sin: by not providing information after hearing a public solemn pledge even though you are a witness, knowing something, or having seen something so that you become liable to punishment;

2 or by touching some unclean thing—the dead body of an unclean wild animal, unclean livestock, or unclean swarming creature—but the fact goes unknown so that you become unclean and guilty of sin;

3 or by touching human uncleanness—any uncleanness that makes one unclean—and the fact goes unknown, but you later learn of it and become guilty of sin;

4 or by carelessly swearing to do something, whether bad or good—whatever one might swear carelessly—and the fact goes unknown, but you later learn of it and become guilty of sin concerning one of these things—

5 at that point, when you have become guilty of sin in one of these ways, you must confess how you have sinned
