Chatterers

Pindar, Olympian Odes 2.86-88 (tr. Anthony Verity):

Wise is the man who knows much by nature,
while those who have acquired their knowledge
chatter in pointless confusion, just like
a pair of crows against the divine bird of Zeus.

σοφὸς ὁ πολλὰ εἰδὼς φυᾷ·
μαθόντες δὲ λάβροι
παγγλωσσίᾳ κόρακες ὣς ἄκραντα γαρύετον
Διὸς πρὸς ὄρνιχα θεῖον.

Basil L. Gildersleeve ad loc. (the lines are 94-96 in his numbering):
