In these verses we have,

I.God's promises of succour and comfort to those that consider the poor; and,

1.We may suppose that David makes mention of these with application either, (1.) To his friends, who were kind to him, and very considerate of his case, now that he was in affliction: Blessed is he that considers poor David. Here and there he met with one that sympathized with him, and was concerned for him, and kept up his good opinion of him and respect for him, notwithstanding his afflictions, while his enemies were so insolent and abusive to him; on these he pronounced this blessing, not doubting but that God would recompense to them all the kindness they had done him, particularly when they also came to be in affliction. The provocations which his enemies gave him did but endear his friends so much the more to him. Or, (2.) To himself. He had the testimony of his conscience for him that he had considered the poor, that when he was in honour and power at court he had taken cognizance of the wants and miseries of the poor and had provided for their relief, and therefore was sure God would, according to his promise, strengthen and comfort him in his sickness.

2.We must regard them more generally with application to ourselves. Here is a comment upon that promise, Blessed are the merciful, for they shall obtain mercy. Observe, (1.) What the mercy is which is required of us. It is to consider the poor or afflicted, whether in mind, body, or estate. These we are to consider with prudence and tenderness; we must take notice of their affliction and enquire into their state, must sympathize with them and judge charitably concerning them. We must wisely consider the poor; that is, we must ourselves be instructed by the poverty and affliction of others; it must be Maschil to us, that is the word here used. (2.) What the mercy is that is promised to us if we thus show mercy. He that considers the poor (if he cannot relieve them, yet he considers them, and has a compassionate concern for them, and in relieving them acts considerately and with discretion) shall be considered by his God: he shall not only be recompensed in the resurrection of the just, but he shall be blessed upon the earth This branch of godliness, as much as any, has the promise of the life that now is and is usually recompensed with temporal blessings. Liberality to the poor is the surest and safest way of thriving; such as practise it may be sure of seasonable and effectual relief from God, [1.] In all troubles: He will deliver them in the day of evil, so that when the times are at the worst it shall go well with them, and they shall not fall into the calamities in which others are involved; if any be hidden in the day of the Lord's anger, they shall. Those who thus distinguish themselves from those that have hard hearts God will distinguish from those that have hard usage. Are they in danger? he will preserve and keep them alive; and those who have a thousand times forfeited their lives, as the best have, must acknowledge it as a great favour if they have their lives given them for a prey. He does not say, "They shall be preferred," but, "They shall be preserved and kept alive, when the arrows of death fly thickly round about them." Do their enemies threaten them? God will not deliver them into the will of their enemies; and the most potent enemy we have can have no power against us but what is given him from above. The good-will of a God that loves us is sufficient to secure us from the ill-will of all that hate us, men and devils; and that good-will we may promise ourselves an interest in if we have considered the poor and helped to relieve and rescue them. [2.] Particularly in sickness (Psa 41:3): The Lord will strengthen him, both in body and mind, upon the bed of languishing, on which he had long lain sick, and he will make all his bed - a very condescending expression, alluding to the care of those that nurse and tend sick people, especially of mothers for their children when they are sick, which is to make their beds easy for them; and that bed must needs be well made which God himself has the making of. He will make all his bed from head to foot, so that no part shall be uneasy; he will turn his bed (so the word is), to shake it up and make it very easy; or he will turn it into a bed of health. Note, God has promised his people that he will strengthen them, and make them easy, under their bodily pains and sicknesses. He has not promised that they shall never be sick, nor that they shall not lie long languishing, nor that their sickness shall not be unto death; but he has promised to enable them to bear their affliction with patience, and cheerfully to wait the issue. The soul shall by his grace be made to dwell at ease when the body lies in pain.

II.David's prayer, directed and encouraged by these promises (Psa 41:4): I said, Heal my soul. It is good for us to keep some account of our prayers, that we may not unsay, in our practices, any thing that we said in our prayers. Here is, 1. His humble petition: Lord be merciful to me. He appeals to mercy, as one that knew he could not stand the test of strict justice. The best saints, even those that have been merciful to the poor, have not made God their debtor, but must throw themselves on his mercy. When we are under the rod we must thus recommend ourselves to the tender mercy of our God: Lord, heal my soul. Sin is the sickness of the soul; pardoning mercy heals it; renewing grace heals it; and this spiritual healing we should be more earnest for than for bodily health. 2. His penitent confession: "I have sinned against thee, and therefore my soul needs healing. I am a sinner, a miserable sinner; therefore, God be merciful to me," Luk 18:13. It does not appear that this has reference to any particular gross act of sin, but, in general, to his many sins of infirmity, which his sickness set in order before him, and the dread of the consequences of which made him pray, Heal my soul.

I said, Lord, be merciful unto me,.... See Gill on Psa 40:11;

heal my soul; not that it was diseased with sin in such sense as the souls of other men are; but it is to be understood as a petition for comfort while bearing the sins of others, and which Christ as man stood in need of when in the garden and on the cross; so healing signifies comfort in trouble, as in Isa 57:18;

for I have sinned against thee; or "unto thee", or "before thee", as the Targum; not that any sin was committed by him in his own person, but he having all the sins of his people on him, which he calls his own, Psa 40:12; he was treated as a sinner, and as guilty before God, Isa 53:12; and so the words may be read, "for I am a sinner unto thee" (u); I am counted as one by thee, having the sins of my people imputed to me; and am bound unto thee, or under obligation to bear the punishment of sin; or thus, "for I have made an offering for sin unto thee" (w), so the word is used, Lev 6:26; and so it might be rendered in Lev 5:7; and perhaps may be better rendered so in Lev 4:3; and be understood, not of the sin of the anointed priest, but of his offering a sacrifice for the soul that sinned through ignorance, Psa 41:2, which offering is directed to: and then the sense here is, heal me, acquit me, discharge me, and deliver me out of this poor and low estate in which I am; for I have made my soul an offering for sin, and thereby have made atonement for all the sins of my people laid upon me; and accordingly he was acquitted and justified, Ti1 3:16.

I said--I asked the mercy I show.

heal my soul--(Compare Psa 30:2). "Sin and suffering are united," is one of the great teachings of the Psalms.
