Should a wise man make answer with vain knowledge, And fill himself with the east wind?

Will a wise man make answer with knowledge of no value, or will he give birth to the east wind?

Επρεπε σοφος να προφερη στοχασμους ματαιους και να γεμιζη την κοιλιαν αυτου απο ανατολικου ανεμου;

Should a wise man utter vain knowledge, and fill his belly with the east wind?
