2 Thessalonians 3:6
Now we command you, brothers, in the name of our Lord Jesus Christ…
The striking word "withdraw" is, in its simple form, found only besides in 2 Corinthians 8:20. In a still more striking compound it occurs in Acts 20:20-27; Galatians 2:12; Hebrews 10:38. It is a metaphor from the language of strategy; a cautious general shrinking from an engagement and timidly drawing off under cover. Perhaps we might illustrate it by the familiar "fight shy." A social excommunication rather than ecclesiastical seems chiefly meant, though the latter might be involved. The word "disorderly" is rendered "unruly" in 1 Thessalonians 5:14. The kind of irregularity is made clear in vers. 10, 11. Bengel quaintly makes this an opportunity for denouncing the Mendicant Orders. "An order of mendicants is not an order; if the Thessalonians had bound themselves to it by a vow, what would Paul have said?"
