2 thes 3:10

If any would not work, neither should he eat - This is a just maxim, and universal nature inculcates it to man. If man will work, he may eat; if he do not work, he neither can eat, nor should he eat. The maxim is founded on these words of the Lord: In the sweat of thy brow thou shall eat bread. Industry is crowned with God's blessing; idleness is loaded with his curse. This maxim was a proverb among the Jews. Men who can work, and will rather support themselves by begging, should not get one morsel of bread. It is a sin to minister to necessities that are merely artificial.

3:10 Work is the appropriate way to gain a living (see Gen 3:17-19; Ps 128:2; Prov 10:4). Paul absolves the church of the responsibility of feeding other believers who refuse to work.

For even when we were with you,.... At Thessalonica in person, and first preached the Gospel to them, we commanded you, that if any would not work, neither should he eat; the Ethiopic version reads in the singular number, "when I was with you, I commanded you"; using the above words, which were a sort of a proverb with the Jews, and is frequently used by them, , or , "that if a man would not work, he should not eat" (q). And again (r), "he that labours on the evening of the sabbath (or on weekdays), he shall eat on the sabbath day; and he who does not labour on the evening of the sabbath, from whence shall he eat (or what right and authority has he to eat) on the sabbath day?'' Not he that could not work through weakness, bodily diseases, or old age, the necessities of such are to be distributed to, and they are to be taken care of, and provided with the necessaries of life by the officers of the church; but those that can work, and will not, ought to starve, for any assistance that should be given them by the members of the church, or the officers of it.
