Charles Ellicott Commentary Ephesians 4:27

"neither give place to the devil." — Ephesians 4:27 (ASV)

Neither give place (that is, scope) to the devil. The name “Devil” is used by Paul only in his later Epistles (1 Timothy 3:6–7; 1 Timothy 6:9; 2 Timothy 2:26; Titus 2:3). In his 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 find the name “Satan,” which also appears, less frequently, in his later Epistles as well (1 Timothy 1:20; 1 Timothy 5:15).

The latter name, “Satan,” simply describes him as “the enemy”; the former, “Devil,” describes one method of his enmity (as “the Tempter” is another), for it signifies “one who sets at variance,” man with God, and man with man.

Since this fiendish work is mostly understood as accomplished through slander, the name “Devil” is commonly taken to mean “the slanderer.” When applied to human beings (as in 1 Timothy 3:11; 2 Timothy 3:3; Titus 2:3), it seems to convey a similar meaning.

But in this context, the original sense of “one who sets at variance” suits the distinctive idea of the passage. In accordance with the general principle noted previously, excessive anger is forbidden, as it gives an opportunity to the enemy, who desires to break up unity and “set at variance” those who should be one in Jesus Christ.
