I don't understand the meaning of Leviticus 5:4:
"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." (KJV 5:4)
What does "and it be hid from him" mean? How can something that a man has pronounced with an oath be hid from him? I can't think of any possible case besides a man being delirious and saying things without realizing it, but, of course, it is not the case here.
