Classic Poem

Well learned are you in Gods sacred lore,
Ah, who for the tru rule doth still implore,
Leaning on nothing but on Gods blest Word,
That guidance truest , surest doth afford:
Ever when as the Carpenter doth square,
Regards he a trew rule , good work to reare:

Call for the trew rule still then, whereby youth
Vertuously may be train'd up in truth;
Regarding which, right Reverend Father deare,
Let none go forth without this rule , to reare,
Ever at all any foundation here.
