Jamieson, Fausset and Brown on 2 Thessalonians 3:10

10. For even--Translate, "For also." We not only set you the example, but gave a positive "command."

commanded--Greek imperfect, "We were commanding"; we kept charge of you.

would not work--Greek, "is unwilling to work." Bengel makes this to be the argument: not that such a one is to have his food withdrawn from him by others; but he proves from the necessity of eating the necessity of working; using this pleasantry, Let him who will not work show himself an angel, that is, do without food as the angels do (but since he cannot do without food, then he ought to be not unwilling to work). It seems to me simpler to take it as a punishment of the idle. Paul often quotes good adages current among the people, stamping them with inspired approval. In the Hebrew, "Bereshith Rabba," the same saying is found; and in the book Zeror, "He who will not work before the sabbath, must not eat on the sabbath."
