For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile:
Will love, х theloon (G2309)] - 'wishes to love.' He who loves life (present and eternal), and desires to continue to do so, not involving himself in troubles which make this life a burden, and involve forfeit of eternal life. Peter confirms 1 Peter 3:9 by Psalms 34:12; Psalms 34:16.
Refrain, х pausatoo (G3973)] - 'cause to cease;' implying that our inclination and custom is to speak evil. 'Men think they would be exposed to the wantonness of enemies if they did not vindicate their rights. But the Spirit promises a life of blessedness to those alone who are patient of evils' (Calvin).
Evil ... guile. First he warns against sins of tongue, evil and double-tongued speaking; next, against acts of injury to one's neighbour.
