Webster(i)
3 Or if he shall touch the uncleanness of man, whatever uncleanness it may be that a man shall be defiled with, and it be hid from him; when he knoweth of it, then he shall be guilty.
4 Or if a soul shall swear, pronouncing with his lips to do evil, or to do good, whatever it may 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.
