Wherefore - as your evil is of yourselves, but your good from God. However, the oldest manuscripts and versions read thus: “YE KNOW IT (so Eph 5:5; Heb 12:17), my beloved brethren; BUT (consequently) let every man be swift to hear,” that is, docile in receiving “the word of truth” (Jam 1:18, Jam 1:21). The true method of hearing is treated in Jam 1:21-27, and Jam 2:1-26.
slow to speak - (Pro 10:19; Pro 17:27, Pro 17:28; Ecc 5:2). A good way of escaping one kind of temptation arising from ourselves (Jam 1:13). Slow to speak authoritatively as a master or teacher of others (compare Jam 3:1): a common Jewish fault: slow also to speak such hasty things of God, as in Jam 1:13. Two ears are given to us, the rabbis observe, but only one tongue: the ears are open and exposed, whereas the tongue is walled in behind the teeth.
slow to wrath - (Jam 3:13, Jam 3:14; Jam 4:5). Slow in becoming heated by debate: another Jewish fault (Rom 2:8), to which much speaking tends. Tittmann thinks not so much “wrath” is meant, as an indignant feeling of fretfulness under the calamities to which the whole of human life is exposed; this accords with the “divers temptations” in Jam 1:2. Hastiness of temper hinders hearing God’s word; so Naaman, 2Ki 5:11; Luk 4:28.
