New International Version - UK
19 Like a broken tooth or a lame foot
is reliance on the unfaithful in a time of trouble.
20 Like one who takes away a garment on a cold day,
or like vinegar poured on a wound,
is one who sings songs to a heavy heart.
21 If your enemy is hungry, give him food to eat;
if he is thirsty, give him water to drink.
