She who overestimates her

.من يستخفّ بقدرة عدوّه دائمًا ما يموت أوّلًا

Si subestimas a tus enemigos,

Si subestimas a tus enemigos,
no durarás mucho.
Ceux qui sous-estiment leurs ennemis
ne font pas long feu.
Chi sottovaluta il nemico muore per primo.
Quem subestima seu
oponente morre primeiro.
Недооценишь врага —
и прощайся с жизнью.
