Leviticus 19:16

16.Thou shalt not go up and down. The principle of the second clause is the same as that of the foregoing verse, for it is added to a general precept, whereby detraction is condemned: and much more ought we to be deterred from it, whilst we acknowledge that our tongue is thus armed cruelly to shed innocent blood. Some suppose that the word רכיל, racil, is metaphorically taken from merchants, because the tale-bearer or whisperer (169) is no less busy in hunting for false reports, which he may afterwards circulate, than the merchant is diligently bent on buying and selling. Others think that there is a change of the letter ג into כ; and that thus the word is derived from the feet; because calumniators are always wandering about to hunt for grounds of detraction; and therefore is always joined with a verb which signifies to walk. I do not think, however, that it is always used in the same sense; for when Ezekiel reproves the Israelites, because there were always men called רכיל, racil, among them, to shed blood, (170) I understand men of fraud, or fraudulent persons, who plot against the good to procure their destruction. ( Ezekiel 22:9.) Some also translate it spies. Meanwhile, I doubt not, but that Moses, in this passage, designates those vagabonds, who too eagerly run about hither and thither, and in their malignant inquisitiveness penetrate into everybody’s secrets, to bring quiet people into trouble. In short, we are taught that they are accounted false witnesses before God, whosoever by the virulence of their tongue bring their brethren into danger and inconvenience.
