Jehovah knoweth the days of the upright [1] It is not without good reason that David so frequently inculcates this doctrine, that the righteous are blessed because God provides for their necessities. We see how prone the minds of men are to distrust, and how much they are vexed by an excess of cares and anxieties from which they are unable to extricate themselves, while, on the other hand, they fall into another error in being more anxious regarding the future than there is any reason for; and yet, however active and industrious in the formation of their plans, they are often disappointed in their expectations, and not unfrequently fail altogether of success. Nothing, therefore, is more profitable for us than to have our eyes continually set upon the providence of God, which alone can best provide for us every thing we need. On this account, David now says, that God knoweth the days of the righteous; that is to say, he is not ignorant of the dangers to which they are exposed, and the help which they need. This doctrine we ought to improve as a source of consolation under every vicissitude which may seem to threaten us with destruction. We may be harassed in various ways, and distracted by many dangers, which every moment threaten us with death, but this consideration ought to prove to us a sufficient ground of comfort, that not only are our days numbered by God, but that he also knows all the vicissitudes of our lot on earth. Since God then so carefully watches over us for the maintenance of our welfare, we ought to enjoy, in this our pilgrimage on earth, as much peace and satisfaction as if we were put in full possession of our paternal inheritance and home. Because we are regarded by God, David from this concludes, that our inheritance is everlasting. Moreover, in declaring that those who are upright are thus carefully protected by God, he exhorts us to the sincere pursuit of truth and uprightness; and if we desire to be placed in safety under the protection of God, let us cultivate meekness, and reject with detestation this hellish proverb, "We must howl among wolves."
1 - "Depositeth the days of the upright," -- lays them up in safety for them: for such is the original idea of yr." -- Fry
The Lord knoweth the days of the upright - See the notes at Psalm 1:6. He knows how long they will live, and all that will happen to them. He sees their whole course of life; he sees the end. It is implied here that his eyes are on all the allotted days of their life; on all that has been ordained for them in the whole course of their life; and that nothing can shorten the days appointed to them. The wicked expect to live, hope to live, make their arrangements to live; but their eyes cannot rest on the future, and they cannot see the end - cannot tell precisely when they will be cut off. Some unexpected calamity - something which they cannot foresee - may come upon them, and cut short their days long before the expected thee; but this cannot happen in respect to Him whose eyes are on the righteous. Nothing can prevent their reaching the thee which he has fixed as the termination of their lives.
And their inheritance shall be forever - Shall be permanent, enduring. Perhaps all that was implied in tiffs language, as it was used by the psalmist, was that they would "continue," or would not be cut off as the wicked are; that is, that righteousness would contribute to length of days upon the earth (compare Psalm 37:9); yet the "language" suggests a higher idea, and is applicable to the righteous in respect to the promise that they will be put in "everlasting" possession of that which they "inherit" from God; that is, that they will be literally blessed forever. They will have a sure inheritance on earth, and it will endure to all eternity in another world.
The Lord knoweth the days of the upright - He is acquainted with all his circumstances, severings, and ability to bear them; and he will either shorten his trials or increase his power. The Lord also approves of the man and his concerns; and his inheritance shall be for ever. He shall have God for his portion, here and hereafter. This is probably another indirect promise to the captives that they shall be restored to their own land. See Psalm 37:11.
The LORD (l) knoweth the days of the upright: and their inheritance shall be for ever.
(l) God knows what dangers hang over his, and by what means to deliver them.
The Lord knoweth the days of the upright,.... Not only how long they shall live, and so fill up their days, the number of them, as Aben Ezra interprets it; but the nature of their days, whether prosperous or adverse; and causes both to work together for their good; and he knows the work of their days, as Jarchi explains it, the actions done by them in faith and love, and to his honour and glory, and which he approves and accepts of in Christ; see Psalm 1:6;
and their inheritance shall be for ever; in heaven, which is an eternal and never fading one, Hebrews 9:15; and therefore they ought not to fret and be envious.
God, who knows His people's changes, provides against evil and supplies all their need.
The life of those who love Jahve with the whole heart is, with all its vicissitudes, an object of His loving regard and of His observant providential care, Psalm 1:6; Psalm 31:8, cf. Psalm 16:1-11. He neither suffers His own to lose their heritage nor to be themselves lost to it. The αἰώνιος κληρονομία is not as yet thought of as extending into the future world, as in the New Testament. In Psalm 37:19 the surviving refers only to this present life.
Knoweth - Observes with care and affection. The days - All things which befal them, their dangers and fears, and suffering. For ever - To them and their seed for ever: and when they die their inheritance is not lost, but exchanged for one infinitely better.
