John Calvin Commentary Psalms 25:22

"Redeem Israel, O God, Out all of his troubles." — Psalms 25:22 (ASV)

Do You, O God! redeem Israel. By this conclusion, David shows the kind of enemies about whom he complained. From this, it would appear that they were domestic enemies who, like some disease raging deep within, were now the cause of trouble and vexation to the people of God.

By the word redeem, which he uses here, we may infer that the Church was at that time oppressed by harsh bondage; and, therefore, I have no doubt that in this psalm, he alludes to Saul and others who reigned with him in a tyrannical manner. At the same time, he shows that he is concerned not merely with his own benefit, but that he includes in his prayer the state of the whole realm, just as the mutual communion and connection that exists among the saints require that every individual, deeply affected by a sense of the public calamities that befall the Church at large, should unite with all the others in lamentation before God.

This contributed significantly to confirm David's faith, as, regarding himself as connected in all things with the whole body of the faithful, he considered that all the afflictions and wrongs he endured were shared with them. And we ought to consider it of the greatest importance that, in accordance with this rule, every one of us, when bewailing our own private miseries and trials, should extend our desires and prayers to the whole Church.
