Jerome : (Verse 10) For the stars of the heavens and their splendor will not extend their light; the sun will be darkened at its rising, and the moon will not shine with its light. The Hebrew word Chisile () was translated as ὠρίωνα in the Septuagint. The Hebrews, with whom I studied, translated it as Arcturus. However, following Symmachus, we generally referred to it as a constellation. The meaning is that when the day of the Lord's cruelty comes and his fury devastates everything, due to the magnitude of fear, all things will become dark for mortals, and even the sun, moon, and shining stars will seem to deny their brightness. And so the sky is clad in darkness, which covers everything, and under the weight of evil, humans feel nothing but what their mind forces them to see. — Commentary on Isaiah Jerome : (Verse 10.) For the stars of heaven and their splendor will not expand their light: the sun will be obscured in its rising, and the moon will not shine in its brightness. LXX: For the stars of heaven and Orion, and all the adornment of the heavens will not give their light (or, will have it): and they will be darkened when the sun rises, and the moon will not give its light. Because we have interpreted the splendor of them, without a doubt the stars Aquila and Theodotion have placed the Hebrew word "Chisileem" (): for which reason the LXX translated it as Orion, adding from their own, and all the adornment of the heavens, which is to be marked with an obelus. The fables of the Gentiles say that Orion has twenty-two stars, of which four are of the third magnitude, nine of the fourth, and again nine of the fifth, and they are called Bootes by others. We also read in Job about the Hyades, the Evening Star, Arcturus, and the treasures or inner parts of the South (Job 9:9), about which will be said in their proper place. Nor should we think that these stars are called by these names among the Hebrews, which the Greek and Latin language sound forth, but they have their own proper names. For just as God called light, day; and firmament, heaven; and dry land, earth; and gatherings of waters, seas (Gen. I); so too he named each star with its own names, the properties of which our language does not express. It is written of God in another place: Who numbers the multitude of stars: and calls each of them by name. Therefore, when the day of the Lord comes to establish the barrenness of the earth and to completely remove sinners from it (Ps. CXLVI, 4); then, in comparison to the divine majesty, the stars of the sky and all their splendor will withdraw their light. And it is no wonder to say this about the lesser stars, since the sun itself becomes obscured at its rising, and the moon does not have its usual radiance. But that which the seventy translators rendered, that the stars and Orion, and all the adornments of the sky are obscured at the rising of the sun, does not have any significance or miracle; for this happens at all times, that when the sun rises, the stars that are in the sky do not appear. It is also not surprising to say this about the sun, since even during a full moon and when the entire night is shining, many stars do not shine. Moreover, it also proves the daily movement of the stars in the sky, as well as the eclipse of the sun, which, as philosophers argue, when the shadow of the earth and the orbit of the moon are obstructed, brighter stars are seen in the sky. — Commentary on Isaiah
