King James Version
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.New International Version
"'Or if a person thoughtlessly takes an oath to do anything, whether good or evil-in any matter one might carelessly swear about-even though he is unaware of it, in any case when he learns of it he will be guilty.Catholic Public Domain Version
The soul who swears and offers from his own lips that he would do either evil or good, and who will have bound the same with an oath and with his own words, and, having forgotten it, afterwards understands his transgression
