Psalms 23

3. To restore the soul is to revive or quicken it ( Psalms 19:7 ), or relieve it ( Lamentations 1:11 Lamentations 1:19 ).
paths of righteousness--those of safety, as directed by God, and pleasing to Him.
for his name's sake--or, regard for His perfections, pledged for His people's welfare.

4. In the darkest and most trying hour God is near.
the valley of the shadow of death--is a ravine overhung by high precipitous cliffs, filled with dense forests, and well calculated to inspire dread to the timid, and afford a covert to beasts of prey. While expressive of any great danger or cause of terror, it does not exclude the greatest of all, to which it is most popularly applied, and which its terms suggest.
thy rod and thy staff--are symbols of a shepherd's office. By them he guides his sheep.

5, 6. Another figure expresses God's provided care.
a table--or, "food."
oil--anointing oil, the symbol of gladness.
cup (which represents abundance)--are prepared for the child of God, who may feast in spite of his enemies, confident that this favor will ever attend him. This beautiful Psalm most admirably sets before us, in its chief figure, that of a shepherd, the gentle, kind, and sure care extended to God's people, who, as a shepherd, both rules and feeds them. The closing verse shows that the blessings mentioned are spiritual.
