My flesh and my heart faileth - Flesh and heart here seem to refer to the whole man, body and soul; and the idea is, that his powers of body and mind failed; were spent; were exhausted. This seems to have been said in an "ideal" sense, or by anticipation. He does not mean to say that his strength then had actually failed, but he seems to have placed himself by imagination in the situation where his strength "would" be all gone - in sickness, in weakness, in sorrow, on the bed of death. He asks himself now what would be his strength then - what would be the object of chief interest and love - on what he would rely; and he answers without hesitation, and with entire confidence, that he could rely on God, and that He would be his portion forever. Even then, when heart and flesh should fail, when all the powers of mind and body should be exhausted, the love of God would survive, and he would find strength and joy in Him.

But God is the strength of my heart - Margin, as in Hebrew, "rock;" the rock on which my heart relies; that is, my refuge, my defense. See the notes at Psalm 18:2. Compare Psalm 61:2.

And my portion for ever - The source of my happiness. Not wealth, then; not honor; not earthly friends; not fame - will be my reliance and the ground of my hope; but that which I shall regard as most valuable - my supreme joy and rejoicing - will be the fact that God is my friend and portion. With all the doubts which I have had in regard to the rectitude of his government, I am sure that when I come to die, I shall cling to him as my hope, my joy, my all. My last refuge - my sufficient refuge - is God. When people come to die, they have "no other refuge" but God. Nothing that they can accumulate of this world's goods will meet their needs then, for God only can give strength and comfort on the bed of death. Of each and all, however vigorous they may now be, it will be true that "flesh and heart" will "fail;" of each and all it is true that when this shall occur, none but God can be the portion and the strength of the soul.

My flesh - faileth - I shall soon die: and my heart - even my natural courage, will fail; and no support but what is supernatural will then be available. Therefore, he adds:

God is the strength of my heart - Literally, the rock of my heart.

And my portion - Allusion is here made to the division of the promised land. I ask no inheritance below; I look for one above. I do not look for this in the possession of any place; it is God alone that can content the desires and wishes of an immortal spirit. And even this would not satisfy, had I not the prospect of its being for ever, לעולם leolum, "to eternity!'

My flesh and my heart faileth,.... Either through vehement desires of communion with God deferred, see Psalm 84:2 or through afflictive dispensations of Providence, being smitten and chastened continually, Psalm 73:14, or through inward trials and exercises, by reason of indwelling sin, temptations, and desertions: or rather the words are expressive of the body being emaciated by sickness and diseases; and the heart fainting through fear of death, or rather failing at it, being at the point of death; the heart being, as philosophers say, the first that lives, and the last that dies:

but God is the strength of my heart, or "the rock of my heart" (h); when overwhelmed with distress through outward trouble, or in the lowest condition with respect to spiritual things; when grace is weak, corruptions strong, temptations prevail, and afflictions are many; then does the Lord support and sustain his people, and strengthens them with strength in their souls; and in the moment of death, by showing them that its sting is taken away, and its curse removed; that their souls are going to their Lord, and about to enter into his joy; and that their bodies will rise again glorious and incorruptible:

and my portion for ever; both in life and at death, and to all eternity; this is a very large portion indeed; such who have it inherit all things; yea, it is immense and inconceivable; it is a soul satisfying one, and is safe and secure; it can never be taken away, nor can it be spent; it will last always; see Psalm 142:5.

(h) "rupes cordis mei", Montanus, Musculus, Piscator, Cocceius, "petra cordis mei", Tigurine version, Gejerus, Michaelis; so Ainsworth.

My flesh and my heart faileth: but God is the strength of my heart, and my {o} portion for ever.

(o) He teaches us to deny ourselves, to have God our whole sufficiency, and only contentment.

strength: Heb. rock

26. strength-literally, "rock" (Ps 18:2).

portion-(Ps 16:5; La 3:24).

73:21-28 God would not suffer his people to be tempted, if his grace were not sufficient, not only to save them from harm, but to make them gainers by it. This temptation, the working of envy and discontent, is very painful. In reflecting upon it, the psalmist owns it was his folly and ignorance thus to vex himself. If good men, at any time, through the surprise and strength of temptation, think, or speak, or act amiss, they will reflect upon it with sorrow and shame. We must ascribe our safety in temptation, and our victory, not to our own wisdom, but to the gracious presence of God with us, and Christ's intercession for us. All who commit themselves to God, shall be guided with the counsel both of his word and of his Spirit, the best counsellors here, and shall be received to his glory in another world; the believing hopes and prospects of which will reconcile us to all dark providences. And the psalmist was hereby quickened to cleave the closer to God. Heaven itself could not make us happy without the presence and love of our God. The world and all its glory vanishes. The body will fail by sickness, age, and death; when the flesh fails, the conduct, courage, and comfort fail. But Christ Jesus, our Lord, offers to be all in all to every poor sinner, who renounces all other portions and confidences. By sin we are all far from God. And a profession Christ, if we go on in sin, will increase our condemnation. May we draw near, and keep near, to our God, by faith and prayer, and find it good to do so. Those that with an upright heart put their trust in God, shall never want matter for thanksgiving to him. Blessed Lord, who hast so graciously promised to become our portion in the next world, prevent us from choosing any other in this.
