Psalms 58:5  (King James Version)
Which will not hearken to the voice of charmers, charming never so wisely.

That serpents might be charmed or rendered harmless was well known to the ancients. Virgil, and many others state the fact:--{Frigidus in pratis cantando, rumpitur anguis.} "In the meadows the cold snake is burst by incantation."

charming never so wisely or, be the charmer never so
