Remember this. This verse may be explained in two ways, either that the Lord addresses the Jews, or that he addresses the Gentiles. Men who otherwise are not well instructed in the Law are led into mistakes, because they extinguish that knowledge which God kindles in their hearts; for there is no person who has not some seed of religion implanted in him by nature, but men choke it by their unbelief, or corrupt and debase it by their inventions. On this account we might extend it to the whole human race. But I am more disposed to adopt a different opinion, which is also demanded by the context; for the Prophet will soon afterwards add what does not apply to any but the Jews, whom he calls transgressors, because, having been vanquished by a slight temptation, they revolted from the true God, as if captivity ought to have obliterated from their hearts all the benefits which he had bestowed on them. Since, therefore, they had shaken off the true religion, he sharply rebukes their ingratitude in having been so easily led away to sinful inventions. Return to the heart. [1] By giving them this injunction he means that they are not of sound understanding. Others render it, "Recall." This is feeble and inappropriate, and, a little before, he had bid them remember, and will immediately repeat the same thing. Now, therefore, he rather bids them "return to the heart," because forgetfulness of God's benefits was a sort of madness. Blush. Others render it, "Act a manly part," and derive the word from 'ys, (ish.) Others derive it from 'sys, (ashish,) which means "a foundation;" as if he had said, "Take courage, do not despair of my assistance." But I rather agree with Jerome, who derives it from 's, (esh;) for it is more appropriate, when their disgrace has been exposed, to "be ashamed" than to assume manly courage; though I leave it to every person to form his own judgment. He therefore means that they blush for their madness, ingratitude, and wickedness, so as to return to God. [2]

1 - "Bring (it) again to mind." -- Eng. Ver.

2 - "The verb ht'ssv (hithshteshu) is a hapax legomenon, and admits of several different explanations. Joseph Kimchi derived it from 's (esh,) fire, and explained it to mean, Be inflamed or reddened,' that is, blush.' So the Vulgate, confundamini (be confounded.) The Targum and Jarchi understand it to mean, Fortify or strengthen yourselves,' and connect it with 'ssym, (ashishim,) foundations. (Isaiah 16:7.) Bochart derives it from 'ys, (ish,) a man, and identifies it with the andrizesthe, of 1-Corinthians 16:13." -- Alexander.

Remember this - Bear in mind what is now said of the manner in which idols are made. This is addressed, doubtless, to the Jews, and is designed to keep them from idolatry.
And show yourselves men - Acts as men; throw away the childish trifles of idolaters. The word used here (התאשׁשׁוּ hithe'oshâshû' occurs nowhere else in the Bible. It is according to Gesenius, derived from אישׁ 'ı̂ysh, "a man," and means to act "as a man." A similar word is used in 1-Corinthians 16:13 (ἀνδρίζεσθε andrizesthe, from ἀνήρ anēr, a man), and is correctly rendered there, 'quit you like men.' This Greek word often occurs in the Septuagint. It is used as a translation of אמץ 'âmats, in Joshua 1:6-7, Joshua 1:9, Joshua 1:18; 1-Chronicles 28:20; 2-Chronicles 32:7; Nehemiah 2:1; of גדל gâdal in Ruth 1:12; of חזק châzaq, in Deuteronomy 31:6-7, Deuteronomy 31:23; Joshua 10:25; 2-Kings 2:12; 2-Kings 12:8; 1-Chronicles 28:20, and in several other places. Jerome renders the Hebrew word here, 'Be confounded;' the Septuagint, Στενάξατε Stenachate) - 'Groan;' the Syriac, 'Consider,' or understand. The meaning is, that they were to act as became people - not as children; as became those endowed with an immortal mind, and not as the brutes. So Kimchi renders it: 'Be men, and not brutes, which neither consider nor understand.'
O ye transgressors - Ye who have violated the laws of God by the worship of idols. In the time of Manasseh, the Israelites were much addicted to idolatry, and probably this is to be regarded as addressed to them, and as designed to recall them from it to the worship of the true God.

Show yourselves men - התאששו hithoshashu. This word is rather of doubtful derivation and signification. It occurs only in this place: and some of the ancient interpreters seem to have had something different in their copies. The Vulgate read התבששו hithbosheshu, take shame to yourselves; the Syriac התבוננו hithbonenu, consider with yourselves; the Septuagint στεναξετε· perhaps התאבלו hithabbelu, groan or mourn, within yourselves. Several MSS. read התאוששו hithosheshu, but without any help to the sense.

Remember this, and show yourselves men: bring [it] again to (h) mind, O ye transgressors.
(h) Become wise, meaning, that all idolaters are without wit or sense, like mad men.

Remember this,.... Or "these things", as the Syriac version, concerning the matter of which, and the manner in which idols are made; their impotency to move themselves, and their inability to help their votaries, and the difference between them and the true God:
and show yourselves men; and not brutes, as the makers and worshippers of images are, or show themselves as if they were; who unmanly themselves, and act contrary to the natural reason of mankind: or "be ye strong" (q); so the Targum and Jarchi; fortify yourselves against all temptations to idolatry, and against all the arguments and persuasions of idolaters; or "burn ye" (r) or "be ye inflamed", so Rabenu Hal and Joseph Kimchi; that is, blush and be ashamed at such sottishness and stupidity, as men when they are ashamed look as if their faces were inflamed; so the Vulgate Latin version renders it, "be ye confounded" (s); or the sense is, be fervent in spirit, be fired (t) with zeal for God and his glory, and with indignation against such gross idolatry:
bring it again to mind, O ye transgressors; of the law of God, in this instance of idolatry; meaning either the Babylonians, or rather the Jews, who had been drawn in by them to idolatrous practices; calling upon them to return to their senses; to use and exercise their reason; to recollect and reconsider things, and observe and repent of the folly and wickedness they had been guilty of.
(q) "roborat vos", Pagninus, Tigurine version; so Ben Melech interprets the word. (r) Ardete, "comburite vos", some in Vatablus. (s) "Confundamini", V. L. "et erubescite", Calvin. (t) "Incendimini sive corripimini zelo", Vitringa.

show yourselves men--Renounce the childishness of idolatry as shown in what precedes (1-Corinthians 14:20; 1-Corinthians 16:13; Ephesians 4:14). In order to be manly we must be godly; for man was made "in the image of God," and only rises to his true dignity when joined to God; virtue is derived from the Latin vir, "a man."
bring . . . to mind--rather, "lay it to heart."
transgressors--addressed to the idolaters among the Jews.

The second admonition is addressed to those who would imitate the heathen. "Remember this, and become firm, take it to heart, ye rebellious ones! Remember the beginning from the olden time, that I am God, and none else: Deity, and absolutely none like me: proclaiming the issue from the beginning, and from ancient times what has not yet taken place, saying, My counsel shall stand, and all my good pleasure I carry out: calling a bird of prey from the east, the man of my counsel from a distant land: not only have I spoken, I also bring it; I have purposed it, I also execute it." The object to which "this" points back is the nothingness of idols and idolatry. The persons addressed are the פושׁעים (those apostatizing), but, as התאשׁשׁוּ shows, whether it mean ἀνδιρίζεσθε or κραταιοῦσθε (1-Corinthians 16:13), such as have not yet actually carried out their rebellion or apostasy, but waver between Jehovahism and heathenism, and are inclined to the latter. התאשׁשׁו is hardly a denom. hithpalel of אישׁ in the sense of "man yourselves," since אישׁ, whether it signifies a husband or a social being, or like אנושׁ, a frail or mortal being, is at any rate equivalent to אנשׁ, and therefore never shows the modification u. אשׁשׁ (אשׁה) signifies to be firm, strong, compact; in the piel (rabb.), to be well-grounded; nithpael, to be fortified, established; here hithpoel, "show yourselves firm" (Targ., Jeremiah.: fundamini ne rursum subitus idololatriae vos turbo subvertat). That they may strengthen themselves in faith and fidelity, they are referred to the history of their nation; ראשׁנות are not prophecies given at an earlier time - a meaning which the priora only acquire in such a connection as Isaiah 43:9 - but former occurrences. They are to pass before their minds the earlier history, and indeed "from the olden time." "Remember:" zikhrū is connected with the accusative of the object of remembrance, and כּי points to its result. An earnest and thoughtful study of history would show them that Jehovah alone was El, the absolutely Mighty One, and 'Elōhı̄m, the Being who united in Himself all divine majesty by which reverence was evoked. The participles in Isaiah 46:10, Isaiah 46:11 are attached to the "I" of כּמוני. It is Jehovah, the Incomparable, who has now, as at other times from the very commencement of the new turn in history, predicted the issue of which it would lead, and miqqedem, i.e., long before, predicted things that have not yet occurred, and which therefore lit outside the sphere of human combination - another passage like Isaiah 41:26; Isaiah 45:21, etc., in which what is predicted in these prophecies lays claim to the character of a prediction of long standing, and not of one merely uttered a few years before. The ראשׁית, in which the ראשׁנות are already in progress (Isaiah 42:9), is to be regarded as the prophet's ideal present; for Jehovah not only foretells before the appearance of Cyrus what is to be expected of him, but declares that His determination must be realized, that He will bring to pass everything upon which His will is set, and summons the man upon the stage of history as the instrument of its accomplishment, so that He knew Cyrus before he himself had either consciousness or being (Isaiah 45:4-5). The east is Persis (Isaiah 41:2); and the distant land, the northern part of Media (as in Isaiah 13:5). Cyrus is called an eagle, or, strictly speaking, a bird of prey (‛ayit),
(Note: The resemblance to ἀετός (αἰετός) is merely accidental. This name for the eagle is traceable, like avid, to a root vâ, to move with the swiftness of the wind. This was shown by Passow, compare Kuhn's Zeitschrift, i. 29, where we also find at 10, 126 another but less probable derivation from a root i, to go (compare eva, a course).)
just as in Jeremiah 49:22 and Ezekiel 17:3 Nebuchadnezzar is called a nesher. According to Cyrop. vii. 1, 4, the campaign of Cyrus was ἀετὸς χρυσοῦς ἐπὶ δόρατος μακροῦ ἀνατεταμένος. Instead of עצתו אישׁ, the keri reads more clearly, though quite unnecessarily, (עצתי אישׁ (see e.g., Isaiah 44:26). The correlate אף (Isaiah 46:11), which is only attached to the second verb the second time, affirms that Jehovah does not only the one, but the other also. His word is made by Him into a deed, His idea into a reality. יצר is a word used particularly by Isaiah, to denote the ideal preformation of the future in the mind of God (cf., Isaiah 22:11; Isaiah 37:26). The feminine suffixes refer in a neuter sense to the theme of the prophecy - the overthrow of idolatrous Babel, upon which Cyrus comes down like an eagle, in the strength of Jehovah. So far we have the nota bene for those who are inclined to apostasy. They are to lay to heart the nothingness of the heathen gods, and, on the other hand, the self-manifestation of Jehovah from the olden time, that is to say, of the One God who is now foretelling and carrying out the destruction of the imperial city through the eagle from the east.

Bring it - Think of this again and again, ye who have been guilty of this foolish sin.
