Ephesians 4:27

Neither give place (i.e., scope) to the devil. — The name “Devil” is used by St. Paul only in his later Epistles (see Ephesians 6:11; 1 Timothy 3:6; 1 Timothy 6:9; 2 Timothy 2:26; Titus 2:3); in the earlier Epistles (Romans 16:20; 1 Corinthians 5:5; 1 Corinthians 7:5; 2 Corinthians 2:11; 2 Corinthians 11:14; 2 Corinthians 12:7; 1 Thessalonians 2:18; 2 Thessalonians 2:9) we have the name “Satan,” which is also found, less frequently, in the later also (1 Timothy 1:20; 1 Timothy 5:15). The latter name simply describes him as “the enemy “; the former describes one method of his enmity (as “the Tempter” another), for it signifies “one who sets at variance,” man with God, and man with man. Since this fiendish work is mostly contemplated as wrought by slander, the name is commonly taken to mean “the slanderer;” and when applied to human beings (as in 1 Timothy 3:11; 2 Timothy 3:3; Titus 2:3) it seems to convey some such meaning. But here the original sense suits the distinctive idea of the passage. In accordance with the general principle noted above, excess of wrath is forbidden, as giving opportunity to the enemy, who desires to break up unity, and “set at variance” those who should be one in Jesus Christ.
