μειλιχόμυθος
From LSJ
οὐ δικαίως θάνατον ἔχθουσιν βροτοί, ὅσπερ μέγιστον ῥῦμα τῶν πολλῶν κακῶν → unjustly men hate death, which is the greatest defence against their many ills | men are not right in hating death, which is the greatest succour from our many ills
German (Pape)
[Seite 116] von angenehmer, einschmeichelnder Rede, Greg. Naz.
