Psalms 69:30

The psalmist here, both as a type of Christ and as an example to Christians, concludes a psalm with holy joy and praise which he began with complaints and remonstrances of his griefs. I. He resolves to praise God himself, not doubting but that therein he should be accepted of him (Psa 69:30, Psa 69:31): "I will praise the name of God, not only with my heart, but with my song, and magnify him with thanksgiving;" for he is pleased to reckon himself magnified by the thankful praises of his people. It is intimated that all Christians ought to glorify God with their praises, in psalms, and hymns, and spiritual songs. And this shall please the Lord, through Christ the Mediator of our praises as well as of our prayers, better than the most valuable of the legal sacrifices (Psa 69:31), an ox or bullock. This is a plain intimation that in the days of the Messiah an end should be put, not only to the sacrifices of atonement, but to those of praise and acknowledgment which were instituted by the ceremonial law; and, instead of them, spiritual sacrifices of praise and thanksgiving are accepted - the calves of our lips, not the calves of the stall, Heb 13:15. It is a great comfort to us that humble and thankful praises are more pleasing to God than the most costly pompous sacrifices are or ever were. II.

Spiritual are better than mere material offerings (Psa 40:6; Psa 50:8); hence a promise of the former, and rather contemptuous terms are used of the latter.
