What St Athanasius advised
St Athanasius of Alexandria wrote a letter on praying the Psalms. He gives this one to anyone whose enemies taunt them while people who seemed to be friends spread lies about them. He grants that this may grieve them for a while. His answer is to find comfort by praising God in the words of this psalm.
St Athanasius, Letter to Marcellinus on the Psalms (the Greek, from the Thesaurus Linguae Graecae)
Cast your cares on Him
In the Greek Septuagint the prayer’s last verse reads “Cast thy care upon the Lord”, in the English of the translator Lancelot Brenton. His margin sends the reader to St Peter’s first letter, where the same thought comes back in the words “Cast all your anxiety on Him, because He cares for you” (1 Peter 5:7).
The Scripture in it
Listen to my prayer, O God, and do not ignore my plea. Attend to me and answer me. I am restless in my complaint, and distraught
My heart pounds within me, and the terrors of death assail me. Fear and trembling grip me, and horror has overwhelmed me. I said, “Oh, that I had wings like a dove! I would fly away and find rest. How far away I would flee! In the wilderness I would remain. Selah I would hurry to my shelter, far from this raging tempest.”
For it is not an enemy who insults me; that I could endure. It is not a foe who rises against me; from him I could hide. But it is you, a man like myself, my companion and close friend. We shared sweet fellowship together; we walked with the crowd into the house of God.
But I call to God, and the LORD saves me. Morning, noon, and night, I cry out in distress, and He hears my voice.
My companion attacks his friends; he violates his covenant. His speech is smooth as butter, but war is in his heart. His words are softer than oil, yet they are swords unsheathed. Cast your burden upon the LORD and He will sustain you; He will never let the righteous be shaken.
