O God, why hast thou cast us off for ever? - Thou seemest to have cast us off forever, or finally. Compare Psalms 44:9, note; Psalms 13:1, note. “Why doth thine anger smoke.” See Deuteronomy 29:20. The presence of smoke indicates fire, and the language here is such as often occurs in the Scriptures, when anger or wrath is compared with fire. See Deuteronomy 32:22; Jeremiah 15:14.
Against the sheep of thy pasture - Thy people, represented as a flock. See Psalms 79:13; Psalms 95:7. This increases the tenderness of the appeal. The wrath of God seemed to be enkindled against his own people, helpless and defenseless, who needed his care, and who might naturally look for it - as a flock needs the care of a shepherd, and as the care of the shepherd might be expected. He seemed to be angry with his people, and to have cast them off, when they had every reason to anticipate his protection.
