Leviticus 5:4

4 " 'Or suppose a person takes an oath and makes a promise to do something without thinking it through. It does not matter what he promised. It does not matter whether he took the oath without thinking about it carefully. And suppose he is not aware that he did not think it through. When he finds out about it, he will be guilty.

Leviticus 5:4 Meaning and Commentary

Leviticus 5:4

Or if a soul swear
A rash or vain oath:

pronouncing with his lips;
not in his heart, as Jarchi notes; not saying within himself that he would do this, or that, or the other thing, but expressing his oath plainly and distinctly, with an audible voice:

to do good, or to do evil;
which was either impossible or unlawful for him to do; whether the good or evil he swears to do is to himself or to another; whether he swears to do good to himself, and evil to another, or, good to another, and evil to himself, see ( Psalms 15:4 Psalms 15:5 ) . The Targum of Jonathan paraphrases it,

``whatsoever a man expresses, whether of anything present or future;''

as if he swears he has done such and such a thing, whether good or evil; or that he will do it, be it what it will, and it is not in the power of his hands to do it, or, if he did it, it would be doing a wrong thing:

whatsoever [it be] that a man shall pronounce with an oath, and it
be hid from him;
he has forgot that he ever swore such an oath:

and when he knoweth [of it], then he shall be guilty in one of
these;
when he is told of it, and it is made clearly to appear to him, that he did at such a time, and in such a place, deliver out a rash oath concerning this, or the other thing, then he shall be chargeable with guilt in one of these; either in rashly swearing to do good when it was not in his power, or to do evil, which would have been unlawful. The Targum of Jonathan is,

``if he knows that he has falsified, and repents not, he is guilty.''

Leviticus 5:4 In-Context

2 " 'Or suppose a person touches something that is not "clean." It could be the dead bodies of wild animals or of livestock. Or it could be the dead bodies of creatures that move along the ground. Even though he is not aware that he touched them, he has become "unclean." And he is guilty.

3 " 'Or suppose he touches something "unclean" that comes from a human being. It could be anything that would make him "unclean." Suppose he is not aware that he touched it. When he finds out about it, he will be guilty.

4 " 'Or suppose a person takes an oath and makes a promise to do something without thinking it through. It does not matter what he promised. It does not matter whether he took the oath without thinking about it carefully. And suppose he is not aware that he did not think it through. When he finds out about it, he will be guilty.

5 " 'When someone is guilty in any of those ways, he must admit he has sinned.

6 He must bring a sin offering to pay for the sin he has committed. He must bring to the LORD a female lamb or goat from the flock. The priest will sacrifice the animal. That will pay for the person's sin.
