Proverbs 25:19-21 New Revised Standard Version Catholic Edition (NRSVCE)
19 Like a bad tooth or a lame foot
is trust in a faithless person in time of trouble.
20 Like vinegar on a wound
is one who sings songs to a heavy heart.
Like a moth in clothing or a worm in wood,
sorrow gnaws at the human heart.
21 If your enemies are hungry, give them bread to eat;
and if they are thirsty, give them water to drink;
