And the LORD said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof. Set a mark upon the foreheads of the men that sigh - This is in allusion to the ancient every-where-used custom of setting marks on servants and slaves, to distinguish them from others. It was also common for the worshippers of particular idols to have their idol's mark upon their foreheads, arms, etc. These are called sectarian marks to the present day among the Hindoos and others in India. Hence by this mark we can easily know who is a follower of Vishnoo, who of Siva, who of Bramah, etc. The original words, והתוית תו vehithvitha tau, have been translated by the Vulgate, et signa thau, "and mark thou tau on the foreheads," etc. St. Jerome and many others have thought that the letter tau was that which was ordered to be placed on the foreheads of those mourners; and Jerome says, that this Hebrew letter ת tau was formerly written like a cross. So then the people were to be signed with the sign of the cross! It is certain that on the ancient Samaritan coins, which are yet extant, the letter ת tau is in the form +, which is what we term St. Andrew's cross. The sense derived from this by many commentators is, that God, having ordered those penitents to be marked with this figure, which is the sign of the cross, intimated that there is no redemption nor saving of life but by the cross of Christ, and that this will avail none but the real penitent. All this is true in itself, but it is not true in respect to this place. The Hebrew words signify literally, thou shalt make a mark, or sign a sign, but give no intimation what that mark or sign was. It was intended here to be what the sprinkling of the blood of the paschal lamb on the lintels and door-posts of the Israelites was, namely, a notice to the destroying angel what house he should spare. As the whole of this matter only passed in vision we are bound to neither letter, nor any other kind of figure. The symbolical action teaches us that God, in general judgments, will make a distinction between the innocent and the guilty, between the penitent and the hardened sinner.
