(40) He shall fly as an eagle . . .--The image, as in Deuteronomy 28:49; Isaiah 46:11; Ezekiel 17:3, was the natural symbol of a fierce invader, probably, in this case, of Nebuchadnezzar. Here it receives a fresh vividness from the previous comparison of Moab to the dove that had its nest in the clefts of the rock. The verse is reproduced in Jeremiah 49:22, in reference to Edom.

Verses 40, 41. - The Septuagint has a shorter form (see introduction to chapter). Verse 40. - He shall fly as an eagle; rather, he shall swoop (same word and figure in Deuteronomy 28:49). The subject is not named, but (as in ch. 46:18) is Nebuchadnezzar.

48:14-47. The destruction of Moab is further prophesied, to awaken them by national repentance and reformation to prevent the trouble, or by a personal repentance and reformation to prepare for it. In reading this long roll of threatenings, and mediating on the terror, it will be of more use to us to keep in view the power of God's anger and the terror of his judgments, and to have our hearts possessed with a holy awe of God and of his wrath, than to search into all the figures and expressions here used. Yet it is not perpetual destruction. The chapter ends with a promise of their return out of captivity in the latter days. Even with Moabites God will not contend for ever, nor be always wroth. The Jews refer it to the days of the Messiah; then the captives of the Gentiles, under the yoke of sin and Satan, shall be brought back by Divine grace, which shall make them free indeed.For thus saith the Lord, behold, he shall fly as an eagle,.... The enemy, Nebuchadnezzar king of Babylon, with his army; who is compared to an eagle for his strength, swiftness, and greediness after the prey:

and shall spread his wings over Moab; as an eagle spreads its wings, which are very large, over the little birds it seizes upon as its prey; so the king of Babylon would bring a numerous army against Moab, and spread it over his country. The Targum is,

"behold, as all eagle which flies, so a king shall come up with his army, and encamp against Moab.''
