2Thessalonians 3:3-6 But the Lord is faithful, who shall stablish you, and keep you from evil. And we have confidence in the Lord touching you, that you both do and will do the things which we command you. And the Lord direct your hearts into the love of God, and into the patient waiting for Christ. Now we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother that walks disorderly, and not after the tradition which he received of us.
‘But the Lord is faithful.’ Twelve times God and Christ are called faithful (Deut. 7:9; Isa. 49:7; 1Cor. 1:9; 10:13; 2Thess. 3:3; Heb. 10:23; 11:11; 1Pet. 4:19; 1Jn. 1:9; Rev. 1:5; 3:14; 19:11).
‘Confidence in the Lord.’ Paul’s threefold confidence: In God to establish and keep saints from evil (3:3). In saints that they will obey (3:4). In God to direct their hearts into deeper love and patience (3:5).
‘Command you, brethren, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother that walks disorderly, and not after the tradition which he received of us.’ Seven parting commands: Withdraw from unruly brothers (3:6). Work or don’t eat (3:11). Work peaceably (3:12). Make your own living. Be not weary in well doing (3:13). Have no fellowship with rebels (3:14). Admonish rebels (3:15).
‘Disorderly’ [Greek: ataktos] here and 2Thessalonians 3:11 (the verb atakteo, to behave disorderly, is used in 2Thess. 3:7). It means out of order; not in order of battle; not at one’s post of duty; undisciplined; irregular; lawless, and disorderly. They act according to their own wills and are idle busybodies (3:11). Paul here says that he did not go out of his rank or post of duty, but kept his place and discharged his duties at all times and places as a true and tried soldier of Jesus Christ (3:7).
‘Tradition’ [Greek: paradosis] is a handing down; doctrines; traditions (Matt. 15:2-6; Mark 7:3-13; Gal. 1:14; Col. 2:8; 2Thess. 2:15; 3:6). Translated “ordinances” only here. What ordinances he refers to are not listed, but they no doubt include the whole body of truth of the gospel and not only the Lord’s Supper and water baptism.
