John Gill Commentary Ephesians 4:27

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

Neither give place to the devil .
] Or "to the accuser", or "slanderer"; that is, to any adversary, that takes delight in slandering and reproaching the saints; give such no room, nor reason, to calumniate the doctrine and ways of Christ, through an unbecoming conversation, by lying and sinful anger, or by other means;

or rather the devil, the great accuser of the brethren is meant; and the Ethiopic version renders it, "do not give way to Satan"; which is done, when men indulge any lust or corruption; and when they easily fall in with his suggestions and temptations; when they are off of their watch and guard; and when they do not resist, but quietly yield to him.
