Psalm 40 (39):11Meaning & Commentary from the Church Fathers

I will not conceal Your truth within my heart. He comprehends the truth that has been proclaimed to him, a truth that transcends the Law and its mere shadows. When it is stated, "Thou hast understood," it signifies, "You have learned it for yourself." I have embraced Your truth and Your salvation, meaning I have not remained silent; I have made Your truth known. He refers to the preaching of the Gospel as 'truth.' Furthermore, I have neither hidden Your salvation, which is the path to the deliverance You have provided, nor the grace that is received through faith. The term 'Sonm' often denotes the Church composed of both Israelites and Gentiles. Through Christ, the principles of grace and truth, as well as the doctrine of salvation, are revealed to human understanding. Individuals discover the doctrine of truth in thoughtful contemplation and the doctrine of salvation through their active expressions of faith.

A person who places their trust in God and professes that through this faith they shall be recognized as righteous can freely proclaim their righteousness. Christ arrived to affirm faith and provide forgiveness.

The blessed David pledges to proclaim God's truth, the message of prophecy, the wonderful gift of salvation, and boundless mercy within the great Church, which has been united by divine grace across all creation. Furthermore, redeemed creation itself vows to offer this very reward for its deliverance: to build up the Church, to inspire songs of praise, to declare God's righteous judgment, to witness the unfathomable faithfulness, and to validate the truth of prophetic declarations. The phrase "of the hosts of many" is rendered by Symmachus as "in multitude," while Aquila and Theodotion refer to it as "in the great Church," indicating that it is indeed the same Church that is being referenced.

David expresses the profound essence of the gospel when he declares that God’s truth is not concealed in his heart. The Father affirms that He has openly proclaimed the teachings of the gospel to everyone. This truth, along with salvation, is central to the gospel message. It is rich in veracity; as stated, “I, saith He, speak the truth unto you” (John 16:7). Furthermore, it encompasses salvation, offering hope to all who place their faith in Him. Christ emphasizes that He will not withhold His compassion and truth from the masses; the gospel is deemed mercy for the kindness that God has extended to us, as He refrained from allowing His creations to suffer under the oppression of the enemy. Therefore, He willingly gave His only Son to die for our redemption. In this manner, David refers to the gospel by various names, reflecting its diverse blessings.

There are four key motivations for discussing matters of the soul's salvation. The first motivation is liberation—the serene state of the soul that, through diligent effort, has achieved a natural awareness of creation and subsequently delved into the profound depths of theology. The second is the clarity of thought that arises from heartfelt tears and earnest prayer, which gives birth to the message of grace and enables the flow of salvific wisdom. The third reason is the presence of the Holy Trinity within us, from Whom emanates the illumination of the Spirit, benefiting all who are sanctified to reveal the mysteries of the Kingdom of Heaven and uncover the hidden riches of God within the soul.

Once more, the Prophet expressed gratitude to God, seeking to remain in His grace. He emphasizes that his praise and thanksgiving were not only offered in solitude but also proclaimed publicly in the temple, where both words and peace offerings were shared with the assembly. The great congregation he refers to is not merely a common gathering or marketplace meeting but the sacred space where the faithful, upon receiving significant blessings, would traditionally present peace offerings to God. Therefore, in the following verse, he asserts that he did not conceal the truth, meaning God's grace, within his heart, but rather declared it openly for the encouragement of others.
