Thomas Aquinas, on Ps 21:26

“With thee is my praise in a great church: I will pay my vows in the sight of them that fear him.”

“"The poor shall eat." Here next he sets forth the effect of the passion with respect to others; and first he proposes the various effects of the passion; second, he shows that they pertain to the future, at "It shall be proclaimed." Regarding the first, he does two things. First, he proposes the effects pertaining to the apostles. Second, he presents such effects as derived through the apostles to others, at "They shall remember." To the apostles pertains the ministry of the Lord's sacrament, which is designated when he says, "The poor shall eat," that is, the humble and those who despise the things of the world: Mt. 5: "Blessed are the poor in spirit, for theirs is the kingdom of heaven." They shall eat the sacrifice, that is, the sacrament of the body and blood, both sacramentally and spiritually. And from this follows a threefold effect: spiritual, namely satiety, praise, and life. Regarding the first he says, "And they shall be satisfied," because their desire will rest in the fullness of graces that are acquired through this sacrament: Ps. 62: "Let my soul be filled as with marrow and fatness." Regarding the second he says, "And they shall praise the Lord who seek him." Nor is this surprising, because praise follows from joy: Is. 51: "They shall come to Zion with praise, and everlasting joy shall be upon their heads." Now the satiety of desire causes delight: Is. 55: "Your soul shall delight in richness," that is, in spiritual fatness: Ps. 41: "With the voice of exultation and confession, the sound of one feasting." But not just anyone praises God, but "those who seek him," that is, who seek nothing else but Christ or God: Is. 55: "Seek God while he may be found; call upon him while he is near." Regarding the third he says, "Their hearts shall live," etc. Jn. 6: "If anyone eats of this bread, he shall live forever." And therefore he says, "shall live"; as if to say: although they may die in body by imitating the passion of the Lord, yet they shall live in heart: Ps. 68: "Seek the Lord, and your soul shall live."”
