Gregofacsimil + neumes from H + rsigns according to H. Modern verse, with neumes from the original.

"in" is semantically equivalent to the modern "de" and is not melodically equivalent because of the liquescence => "in" is preferred

Updated verse, using dcrochu's idea but putting the mediant in a different place cognizant with the modern interpretation of this verse where "pusilli et magni" is thought to refer to "qui timetis" only, not "sancti ejus". Also backported syllabisation and spacing.
