tiny detail

Goblet: 2:58 The true proclaimer, the prophet, as well as the person of true wisdom does not disdain to give an allegory (comparison) as a means of instruction, may it be ever so small as a gnat or a tiny detail, because it bears witness to the truth for those who are learning and also for those who have knowledge about the truth, which can be taught and understood through the allegory (comparison).
