Offer the sacrifices of righteousness, and put your trust in the LORD.
All Commentaries on Psalms 4:5 Go To Psalms 4
Augustine of Hippo
AD 430
7. "Offer the sacrifice of righteousness, and hope in the Lord" (ver. 5). He says the same in another Psalm, "the sacrifice for God is a troubled spirit." Wherefore that this is the sacrifice of righteousness which is offered through repentance it is not unreasonably here understood. For what more righteous, than that each one should be angry with his own sins, rather than those of others, and that in self-punishment he should sacrifice himself unto God? Or are righteous works after repentance the sacrifice of righteousness? For the interposition of Diapsalma not unreasonably perhaps intimates even a transition from the old life to the new life: that on the old man being destroyed or weakened by repentance, the sacrifice of righteousness, according to the regeneration of the new man, may be offered to God; when the soul now cleansed offers and places itself on the altar of faith, to be encompassed by heavenly fire, that is, by the Holy Ghost. So that this may be the meaning, "Offer the sacrifice of righteousness, and hope in the Lord;" that is, live uprightly, and hope for the gift of the Holy Ghost, that the truth, in which you have believed, may shine upon you.
