Psalms 37:39

39The salvation of the righteous is from Jehovah The sum of the whole is, that whatever may happen, the righteous shall be saved, because they are in the hand of God, and can never be forgotten by him. This ought to be particularly noticed, that those who are greatly afflicted may be sustained by the assurance that the salvation which they expect from God is infallibly certain, because God is eternal, and governs the world by his power; as Christ said,

“My Father, who gave them me, is greater than all,”
(John 10:29.)

David still inculcates this principle, that as righteousness is approved of God, it can never happen that he should forsake his faithful servants, and deprive them of his help. He, therefore, exhorts true believers to depend upon God, not only when things prosper according to their desires, but even when they are sorely afflicted. By these words he teaches that it is enough, if God only impart strength to his servants, so that, when severely afflicted and oppressed with anguish, they may not faint under it, or that, when groaning under the weight of severe afflictions, they may not sink under the burden. To the same purpose also is the expression which David uses twice in the last verse, that God will deliver By this he admonishes the children of God to learn patiently to endure afflictions, and that, if God should prolong them, they should often recall this to their remembrance, that after he has tried their patience, he will in the end deliver them.
