‏ Ezekiel 9:4

4 And the Lord said to him: “Cross through the middle of the city, in the center of Jerusalem, and seal a Tau upon the foreheads of the grieving men, who are mourning over all the abominations which are being committed in its midst.” ^{▼▼9:4This sealing of foreheads over those Jews who remained faithful is a foreshadowing of the Seal (Rev 7:3; 14:1) given by God to assist the faithful during the first and second parts of the tribulation.(Conte)
,} ^{▼▼9:4 Mark Thau: Thau, or Tau, is the last letter in the Hebrew alphabet, and signifies a sign, or a mark; which is the reason why some translators render this place set a mark, or mark a mark without specifying what this mark was. But St. Jerome, and other interpreters, conclude it was the form of the letter Thau, which in the ancient Hebrew character, was the form of a cross.(Challoner)}
