ἄτρεστα
From LSJ
ἢν μή τις ὥσπερ σφηκιὰν βλίττῃ με κἀρεθίζῃ → may no one squeeze me and tease me like a wasp | may no one smoke me and tease me like a wasp | but if anyone annoys me and rifles my nest, they'll find a wasp inside | still if you wake a wasps' nest then of wasps you must beware
Russian (Dvoretsky)
ἄτρεστα: adv. без страха, спокойно (ἐν δόμοις ναίειν Eur.).
