Shall not his excellency - His exaltation שׂאת śe'êth from נשׂא nâśâ' to exalt, to lift up), or his majesty, Genesis 49:3.
Make you afraid - Fill you with awe and reverence. Shall it not restrain you from fallacy, from sophisms, and from all presumptuous and unfounded reasoning? The sense here is, that a sense of the greatness and majesty of God should fill the mind with solemnity and reverence, and make us serious and sincere; should repress all declamation and mere assertion, and should lead us to adduce only those considerations which will bear the test of the final trial. The general proposition, however, is not less clear, that a sense of the majesty and glory of God should at all times fill the mind with solemn awe, and produce the deepest veneration. See Jeremiah 5:22; Jeremiah 10:7-10; Genesis 28:17.
And his dread - The fear of him. You should so stand in awe of him as not to advance any sentiments which he will not approve, or which will not bear the test of examination. Rosenmuller, however, and after him Noyes, supposes that this is not so much a declaration of what ought to be, implying that the fear of God ought to produce veneration, as a declaration of what actually occurred - implying that they were actually influenced by this slavish fear in what they said. According to this it means that they were actuated only by a dread of what God would do to them that led them to condemn. Job without proof, and not by a regard to truth. But the common interpretation seems to me most in accordance with the meaning of the passage.

His dread fall upon you? - The very apprehension of his wrath is sufficient to crush you to nothing.

Shall not his excellency make you afraid,.... To commit sin, any sin, and particularly that just mentioned, which they might expect to be reproved for; there is an excellency in the name of God, which is fearful and dreadful, and in the nature and perfections of God, his power, justice, and holiness, in which he is glorious and tremendous, and should deter men from sinning against him; and there is an excellency in his works of nature and providence, which are wondrous, and show him to be near at hand, and can at once, if he pleases, take vengeance for sin: or "shall not his height" (b), &c. his sublimity, his superiority to all beings; he is the most high God, higher than the highest among men, he is above all gods, all that are so called; and therefore all the inhabitants of the earth should stand in awe of him, and not sin: or "shall not his lifting up" (c)? &c. on a throne of judgment, as the Targum adds; he is the Judge of the whole earth, and will judge his people, and right their wrongs; he sits on a throne high, and lifted up, judging righteously; and will maintain the cause of the innocent, and avenge himself on those that injure them, and therefore it must be a fearful thing to fall into his hands: some render it, "shall not his burning" (d); or flaming fire, &c. as Jarchi observes, and apply it to hell fire, and the everlasting burnings of the lake which burns with fire and brimstone; and which are very terrible, and may well frighten men from sinning against God; but the first sense seems to be best:
and his dread fall upon you? the dread of men, of powerful and victorious enemies, is very terrible, as was the dread of the Israelites which fell upon the inhabitants of Canaan, Joshua 2:9; but how awful must be the terror of the great and dreadful God, when that falls upon men, or his terrible wrath and vengeance are revealed from heaven, and threaten every moment to fall upon the transgressors of his law, upon those that mock him and injure his people.

make you afraid?--namely, of employing sophisms in His name (Jeremiah 10:7, Jeremiah 10:10).
