Read Luke 6:29 Using Other Translations
And unto him that smiteth thee on the one cheek offer also the other; and him that taketh away thy cloke forbid not to take thy coat also.
To one who strikes you on the cheek, offer the other also, and from one who takes away your cloak do not withhold your tunic either.
If someone slaps you on one cheek, offer the other cheek also. If someone demands your coat, offer your shirt also.
