“From one who takes away your cloak do not withhold your tunic either”
If someone strikes you on one cheek, turn to him the other also. And if someone takes your cloak, do not withhold your tunic as well. (Luke 6:29 BSB)
What it sounds like today
Identical to Matthew's saying, at a glance.
The cultural key
The garments are reversed, and the swap changes the scene. Matthew has tunic first, then cloak: a lawsuit, where a creditor sues for the inner garment because the outer cloak was legally protected collateral (Exodus 22:26). Luke has cloak first, then tunic: a robbery, because a thief grabs the outer garment first; it comes off first. Luke also drops the 'right cheek' detail, so the backhand-insult reading (see the Matthew entry) has no anchor here; his version is generalized for readers unfamiliar with Jewish pledge law.
Recovered meaning
Same radical instruction, two different assaults: Matthew's man is being legally stripped, Luke's is being mugged. In both, the response refuses the script: surrender more than was taken and keep your agency. The courtroom-shaming subtext belongs to Matthew's version only.
