The Scryer & the Shewstone

Uriel, your voice is clearly heard
 To tell the toiler's love which can reveal the holy word
 Oh sweet word, to cube the stolen square
 When set upon the holy seals, and Michael shall appear
 Come Michael, great sword be brought to rest
 Lay on your enlightenment and approve the holy quest
 Sum by sum, the characters are given
 A charge of how the rule of God should pass to Earth from Heaven
 [?], the language Michael sends
 It is too alien and too complex to comprehend
 One thing is, yet one can be yet known
 The hand of God is on the hand that shall receive the stone
 Gabriel, the keys you now declare
 Will open God's storehouses for the treasures that lay there
 Enter wisely, humbly, patiently
 What Adam and Enoch knew may now be known to thee
