2 Thessalonians 3:13

“But ye, brethren, &c.] The rest of the members of the church, who were diligent and industrious in their callings, minded their own business, and did not trouble themselves with other men's matters, took care of themselves, and their families, and were beneficent to others: be not weary in well doing; which may be understood generally of all well doing, or of doing of every good work; which is well done when done according to the will of God, in faith, and from a principle of love, and in the name and strength of Christ, and with a view to the glory of God: or particularly of acts of beneficence to the poor; for though the idle and lazy should not be relieved, yet the helpless poor should…”

They would not labor; they spent their time in intermeddling with the concerns of their neighbors, and they depended for their support on the charity of others. The tendency of this, as all persons feel who have ever been applied to by such persons for aid, is, to indispose us to do good to any. We almost insensibly feel that…”

“3:13 doing good: The Thessalonians were exhorted to reach out and help those in genuine need (see Gal 6:9-10), in contrast with those who are lazy and dependent (2 Thes 3:7-8, 10).”
