Be the heaven, that is over thee, of brass: and the ground thou treadest on, of iron.

And thy heavens which are over thy head shall be brass, and the earth which is under thee, iron.

And the heaven over your heads will be brass, and the earth under you hard as iron.

Your sky that is over your head shall be bronze, and the earth that is under you shall be iron.

May the heavens which are above you be of brass, and may the ground upon which you tread be of iron.

Eruntque coeli tui qui sunt supra caput tuam, aerei: et terra, quae est subter te, ferrea.

And thy heaven that is over thy head. He enumerates other causes of barrenness, and especially drought. Often does God by the Prophets, desirous of giving a token of His favor towards the people, promise them the rain of autumn and of spring: the one immediately following the sowing, the other giving growth to the fruits before they begin to ripen; whilst in many passages He also threatens that it should be withheld. To this refers what He now says, that the heavens shall be of brass, and the earth of iron, because neither shall the moisture descend from heaven to fertilize the earth, whilst the earth, bound up and hardened, shall have no juice or dampness in order to production. Whence we gather, that not even a drop of rain falls to the earth except distilled by God, and that whenever it rains, the earth is irrigated as if by His hand. It must, however, be observed, as we have seen before, that the land of Canaan was not like Egypt, which was watered by the care and industry of man, but fertilized by the bounty of heaven. Thus God, by the Prophet, marks the degrees which are worthy of observation, viz., that when He is reconciled to His people, He will "hear the heavens, and they shall hear the earth; and the earth shall hear the corn, and the wine, and the oil;" so that, finally, all these things shall hear starving men. [1] (Hosea 2:21, 22.) It is not superfluous that He should expressly speak of the "heaven over our head," and the earth that is "under our feet," for He thus indicates that His weapons are prepared both above and below to execute His vengeance, so as to assail the people on all sides. Another Prophet confirms this, although only in a brief allusion: "Therefore the heaven over you is stayed from dew, and the earth is stayed from her fruit; and I called for a drought," etc. (Haggai 1:10, 11.) Another mode of expression is then used to make the same thing more sure, viz., that the rain should be turned into "powder and dust;" still this clause may be explained in two ways, either that the rain shall no more fertilize the ground than as if it were ashes; or that, instead of rain, dust should fall, as though God would dry up the rich soil by scattering ashes on it.

Thy heaven - shall be brass, and the earth - iron - The atmosphere should not be replenished with aqueous vapours, in consequence of which they should have neither the early nor the latter rain; hence the earth - the ground, must be wholly intractable, and, through its hardness, incapable of cultivation. God shows them by this that he is Lord of nature; and that drought and sterility are not casualties, but proceed from the immediate appointment of the Lord.

And thy heaven that [is] over thy head shall be (k) brass, and the earth that is under thee [shall be] iron.
(k) It will give you no more moisture than if it were of brass.

And the heaven that is over thy head shall be brass,.... Or like brass, not for its clearness, brightness, and splendour, or for its being spread out like a molten looking glass which was of brass, Job 37:18; but for its dryness and hardness, no moisture being in it, or passing through it; no showers of rain nor dew being let down from it:
and the earth that is under thee shall be iron; or like iron, hard and impenetrable, into which the plough and spade will not enter; nor anything spring out of it, for want of rain and dew to moisten and soften it. The same is said in Leviticus 26:19; only there is an inversion of the figures; there the heaven is said to be as iron, and the earth like brass, but signify the same thing.

heaven . . . brass . . . earth . . . iron--strong Oriental figures used to describe the effects of long-continued drought. This want of regular and seasonable rain is allowed by the most intelligent observers to be one great cause of the present sterility of Palestine.

Brass - Like brass, hard and dry, and shut up from giving rain. Iron - Hard and chapt and barren.
