Charles Ellicott Commentary Proverbs 12:26

"The righteous is a guide to his neighbor; But the way of the wicked causeth them to err." — Proverbs 12:26 (ASV)

The righteous is more excellent than his neighbour. —Though, perhaps, inferior to him in worldly advantages. Or, it may signify that the just man is a guide to his neighbour, showing him the way in which he should walk; the wicked, on the other hand, so far from guiding others, himself helplessly wanders.
