22. That in this sign of the Cross is salvation for all people who are marked on their foreheads. 4079 In Ezekiel the Lord says: “Pass through the midst of Jerusalem, and thou shalt mark the sign upon the men’s foreheads, who groan and grieve for the iniquities which are done in the midst of them.” 4080 Also in the same place:  “Go and smite, and do not spare your eyes. Have no pity on the old man, and the youth, and the virgin, and slay little children and women, that they may be utterly destroyed. But ye shall not touch any one upon whom the sign is written, and begin with my holy places themselves.” 4081 Also in Exodus God says to Moses: “And there shall be blood for a sign to you upon the houses wherein ye shall be; and I will look on the blood, and will protect you. And there shall not be in you the plague of wasting when I shall smite the land of Egypt.” 4082 Also in the Apocalypse:  “And I saw 4083 a Lamb standing on Mount Sion, and with Him a hundred and forty and four thousand; and they had His name and the name of His Father written on their foreheads.” 4084 Also in the same place:  “I am Alpha and Omega, the first and the last, the beginning and the end. Blessed are they that do His commandments, that they may have power over the tree of life.” 4085 4079     [i.e., baptized; but probably after immersion this symbolic ceremony was already in use.] 4080     Ezek. ix. 4 . 4081     Ezek. ix. 4–6 . 4082     Ex. xii. 13 . 4083     “And behold,” Oxford text. 4084     Rev. xiv. 1 . 4085     Rev. xxii. 13, 14 .
