3 The Lord will strengthen him upon the bed of languishing: thou wilt make  all his bed in his sickness.
3 The Lord sustains them on their sickbed and restores them from their bed of illness.
3 The Lord sustains him on his sickbed; in his illness you restore him to full health.
3 Whenever we're sick and in bed, God becomes our nurse, nurses us back to health.
3 The Lord will strengthen him on his bed of illness; You will sustain him on his sickbed.
3 The Lord nurses them when they are sick and restores them to health.
Matthew Henry's Commentary on Psalm 41:3
Commentary on Psalm 41:1-4
(Read Psalm 41:1-4)
The people of God are not free from poverty, sickness, or outward affliction, but the Lord will consider their case, and send due supplies. From his Lord's example the believer learns to consider his poor and afflicted brethren. This branch of godliness is usually recompensed with temporal blessings. But nothing is so distressing to the contrite believer, as a fear or sense of the Divine displeasure, or of sin in his heart. Sin is the sickness of the soul; pardoning mercy heals it, renewing grace heals it, and for this spiritual healing we should be more earnest than for bodily health.
