But the midday or nightly rest is intended to fit for effort, and so a second little picture follows in ver. 3, presenting another aspect of the shepherd's care and of the sheep's course. Out again on to the road, in spite of heat and dust, the flock goes. "Paths of righteousness" is perhaps best taken as "straight paths," as that rendering keeps within the bounds of the metaphor; but since the sheep are men, straight paths for them must needs be paths of righteousness. That guidance is "for His name's sake." God has regard to His revealed character in shepherding His lamb, and will give direction because He is what He is, and in order that He may be known to be what He has declared Himself. The psalmist had learned the purpose of repose and refreshment which, in all regions of life, are intended to prepare for tasks and marches. We are to "drink for strength, and not for drunkenness." A man may lie in a bath till strength is diminished, or may take his plunge and come from it braced for work. In the religious life it is possible to commit an analogous error, and to prize so unwisely peaceful hours of communion, as to waive imperative duty for the sake of them; like Peter with his "Let us make here three tabernacles," while there were devil-ridden sufferers waiting to be healed down on the plain. Moments of devotion, which do not prepare for hours of practical righteousness, are very untrustworthy. But, on the other hand, the paths of righteousness will not be trodden by those who have known nothing of the green pastures and waters where the wearied can rest.
