Psalms 41:13

We complain, and justly, of the want of sincerity, and that there is scarcely any true friendship to be found among men; but the former days were no better. One particularly, in whom David had reposed great confidence, took part with his enemies. And let us not think it strange, if we receive evil from those we suppose to be friends. Have not we ourselves thus broken our words toward God? We eat of his bread daily, yet lift up the heel against him. But though we may not take pleasure in the fall of our enemies, we may take pleasure in the making vain their designs. When we can discern the Lord's favour in any mercy, personal or public, that doubles it. If the grace of God did not take constant care of us, we should not be upheld. But let us, while on earth, give heartfelt assent to those praises which the redeemed on earth and in heaven render to their God and Saviour.

The Psalm ends with a doxology. Blessed be the Lord, i.e., let him be glorified. The blessing at the beginning from the mouth of God is returned from the mouth of his servant. We cannot add to the Lord's blessedness, but we can pour out our grateful wishes, and these he accepts, as we receive little presents of flowers from children who love us. Jehovah is the personal name of our God. God of Israel is his covenant title, and shows his special relation to his elect people. From everlasting and to everlasting. The strongest way of expressing endless duration. We die, but the glory of God goes on and on without pause. Amen and amen. So let it surely, firmly, and eternally be. Thus the people joined in the Psalm by a double shout of holy affirmation; let us unite in it with all out hearts. This last verse may serve for the prayer of the universal church in all ages, but none can sing it so sweetly as those who have experienced as David did the faithfulness of God in times of extremity.
