New Defender's Study Bible Notes
17:27 spareth his words. Christians need to cultivate the grace of quietness. “Be not rash with thy mouth” (Ecclesiastes 5:2), for “every idle word that men shall speak, they shall give account thereof in the day of judgment” (Matthew 12:36). Note also I Thessalonians 4:11; James 1:19; Ephesians 5:4; etc. The book of Proverbs contains many sayings to this effect (Proverbs 13:2; 15:2; 17:28; 21:23; etc).
