Neither did we eat any man's bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:
Eat any man's bread - Greek, 'eat bread from any man;' i:e., live at anyone's expense. Contrast 2 Thessalonians 3:12, "eat THEIR OWN bread."
Wrought (Acts 20:34). In both letters they state they maintained themselves by labour; but in this second letter they do so to offer an example to the idle; whereas, in the first, their object is to vindicate themselves from imputation of mercenary motives in preaching (1 Thessalonians 2:5; 1 Thessalonians 2:9) (Edmunds).
Labour and travail - `toil and hardship' (note, 1 Thessalonians 2:9).
Night and day - scarcely allowing time for repose.
Chargeable - Greek, 'burdensome.' It is at the very time and place of writing these letters that Paul is said to have worked at tent-making with Aquila: an undesigned coincidence.
