And unto man he said - At what time, or how, Job does not say. Prof. Lee supposes that this refers to the instruction which God gave in Paradise to our first parents; but it may rather be supposed to refer to the universal tenor of the divine communications to man, and to all that God had said about the way of true wisdom. The meaning is, that the substance of all that God had said to man was, that true wisdom was to be found in profound veneration of him.
The fear of the Lord, that is wisdom - The word “Lord” here is improperly printed in small capitals, as if the word were יהוה yehovâh. The original word is, however, אדני 'ǎdonāy; and the fact is worthy of notice, because one point of the argument respecting the date of the book turns on the question whether the word Yahweh occurs in it; see the notes at Job 12:9. The fear of the Lord is often represented as true wisdom; Proverbs 1:7; Proverbs 14:27; Proverbs 15:33; Proverbs 19:23; Psalms 111:10, et al. The meaning here is, that real wisdom is connected with a proper veneration for God, and with submission to him. We cannot understand his ways. Science cannot conduct us up to a full explanation of his government, nor can the most profound investigations disclose all that we would wish to know about God. In these circumstances, true wisdom is found in humble piety; in reverence for the name and perfections of God; in that veneration which leads us to adore him, and to believe that he is right, though clouds and darkness are round about him. To this conclusion Job, in all his perplexities, comes, and here his mind finds rest.
And to depart from evil is understanding - To forsake every evil way must be wise. In doing that, man knows that he cannot err. He walks safely who abandons sin, and in forsaking every evil way he knows that he cannot but be right. He may be in error when speculating about God, and the reasons of his government; he may be led astray when endeavoring to comprehend his dealings; but there can be no such perplexity in departing from evil. There he knows he is right. There his feet are on a rock. It is better to walk surely there than to involve ourselves in perplexity about profound and inscrutable operations of the divine character and government. It may be added here, also, that he who aims to lead a holy life, who has a virtuous heart, and who seeks to do always what is right, will have a clearer view of the government and truth of God, than the most profound intellect can obtain without a heart of piety; and that without that, all the investigations of the most splendid talents will be practically in vain.
