The righteous, and the wise, and their works, are in the hand of God - This is a continuation of the preceding subject; and here the wise man draws a conclusion from what he had seen, and from the well-known character of God, that the righteous, the wise, and their conduct, were all in the hand of God, protected by his power, and safe in his approbation: but we cannot judge from the occurrences which take place in life who are the objects of God's love or displeasure.
