Or if a soul swear, pronouncing with his lips to do evil, or to do good, whatsoever it be that a man shall pronounce with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these. To do evil, or to do good - It is very likely that rash promises are here intended; for if a man vow to do an act that is evil, though it would be criminal to keep such an oath or vow, yet he is guilty because he made it, and therefore must offer the trespass-offering. If he neglect to do the good he has vowed, he is guilty, and must in both cases confess his iniquity, and bring his trespass-offering.
