Psalms 51:19

"Then Thou shalt accept the sacrifice of righteousness" (ver. 19). But now sacrifice for iniquity, to wit, a spirit troubled, and a heart humbled; then the sacrifice of righteousness, praises alone. For, "Blessed they that dwell in Thy house, for ever and ever they shall praise Thee:" for this is the sacrifice of righteousness. "Oblations and holocausts." What are "holocausts"? A whole victim by fire consumed. When a whole beast was laid upon the altar with fire to be consumed, it was called a holocaust. May divine fire take us up whole, and that fervour catch us whole. What fervour? "Neither is there that hideth himself from the heat thereof." What fervour? That whereof speaketh the Apostle: "In spirit fervent." Be not merely our soul taken up by that divine fire of wisdom, but also our body; that it may earn their immortality; so be it lifted up for a holocaust, that death be swallowed into victory. "Oblations and holocausts." "Then shall they lay upon thine altar calves." Whence "calves"? What shall He therein choose? Will it be the innocence of the new age, or necks freed from the yoke of the law? ...

Then shall thou be pleased with the sacrifices of righteousness,....

The sense of God's goodness to them would enlarge their hearts in all the instances and expressions of thankfulness and obedience. They will then come to his tabernacle with burnt-offerings, with whole burnt-offerings, which were intended purely for the glory of God, and they shall offer, not lambs and rams only, but bullocks, the costliest sacrifices, upon his altar.

In those days of joyful prosperity thy saints shall present in great abundance the richest and holiest thank offerings to thee, and thou shalt be pleased to accept them. A saved soul expects to see its prayers answered in a revived church, and then is assured that God will be greatly glorified. Though we bring no more sacrifices for sin, yet as priests unto God our solemn praises and votive gifts are thank offerings acceptable to God by Jesus Christ. We bring not the Lord our least things—our doves and pigeons; but we present him with our best possessions—our bullocks. We are glad that in this present time we are able to fulfil in person the declaration of this verse: we also, forecasting the future, wait for days of the divine presence, when the church of God, with unspeakable joy, shall offer gifts upon the altar of God, which will far eclipse anything beheld in these less enthusiastic days. Hasten it, O Lord.

Then shalt thou be pleased with the sacrifices of righteousness - “Then,” that is, when God should have thus showed favor to Zion; when he should have poured out his blessing on Jerusalem; when religion should prosper and prevail; when there should be an increase of the pure worship of God. In such offerings as would “then” be made - in sacrifices presented not in mere form, but with sincerity, humility, and penitence - in the outward offering of blood presented with a corresponding sincerity of feeling, and with true contrition, and a proper acknowledgment of the guilt designed to be represented by the shedding of blood in sacrifice - God would be pleased, and would approve the worship thus rendered to him. Sacrifice would then be acceptable, for it would not be presented as a mere form, but would be so offered, that it might be called a “sacrifice of righteousness” - a sacrifice offered with a right spirit; in a manner which God would deem right. With burnt-offering - See the notes at Isa 1:11. And whole burnt-offering - The word here means that which is wholly consumed, no part of which was reserved to be eaten by the priests, as was the case in many of the sacrifices. See Deu 33:10. Compare Lev 6:9; Lev 1:3-17. Then shall they offer bullocks upon thine altar - That is, then shall bullocks be offered. The meaning is, that all the offerings prescribed in the law would then be brought, and that those sacrifices would be made with a right spirit - a spirit of true devotion - the offering of the heart accompanying the outward form. In other words, there would be manifested the spirit of humble worship; of pure religion.
