George Haydock's Catholic Commentary
Psalms 57:12
PSALM LVII. (SI VERE UTIQUE.)
David reproveth the wicked, and foretelleth their punishment.
A God. Hebrew Elohim shophetim. Both are in the plural, which has induced many to suppose that angels, &c., are meant; yet the plural is sometimes used, when speaking of the true God, Genesis xx. 13., and Josue xxiv. 19. (Calmet) --- Houbigant translates, "gods," which he explains of the pastors of the Church, or "judges." The reward of virtue, and punishment of vice, are very important truths. Let us wait till the time of harvest, and all will be in its proper place. (Berthier)
