Figure 34 shown here is taken directly from Duncan's Masonic Ritual and Monitor (3rd Edition). It pictures the Royal Arch Mason performing the magical Sign of the Master of the Second Veil, which I informally and more informatively call here the Sign of the Hidden Hand of the Men of Jahbuhlun.
According to Duncan's the candidate presents this sign when he is approached by three sojourners from Babylon. Their objective: Rebuild the Temple of Solomon in Jerusalem and eventually establish a world empire of the Jews.
In his teaching course on Ancient Masonry, C.C. Zain of The Brotherhood of Light explains that the ritual for this degree requires a keen understanding of astrology. But, its performance is said to be derived from a passage in the scriptures. "The sign is made," writes Zain, "by thrusting the hand into the bosom and again drawing it out."9 The official Masonic explanation for this sign—a myth intended to divert the profane from the truth — is that it refers to the fourth chapter of Exodus in the Bible :
"And the Lord said unto Moses, put now thine hand into thy bosom; and he put his hand into his bosom; and when he took it out, behold his hand was leprous as snow."
Leprous, indeed, is the hand of the Mason who vainly seeks to hide and coverup his fides oath of allegiance to Jahbuhlun, his sacred God. But, believe me, there is no relationship of the Mason to Moses, a prophet of God who loyally worshipped the true I AM, the God who reigns for all eternity in heaven.
