By another metaphor he expresses the same thing. By horn he means power, as all who are in any measure acquainted with Scripture well know that by this word is set forth power, strength, or any defense for the protection of a nation. He then says that the horn of Moab was cut off; and he adds afterwards as all explanation, that his strength was broken Hence by this second clause we understand what the Prophet meant when he said, that the horn of Moab was cut off. But he again introduces God as the speaker, because the Moabites thought that their horn could not be broken. As then Jeremiah would not have obtained credit, had he spoken in his own name, he again brought forward God as declaring his own words. It now follows, --

The horn - i. e., his pride (marginal reference); his arm, i. e., his strength Jeremiah 17:5.

The horn of Moab is cut off, and his arm is broken - His political and physical powers are no more.

The (n) horn of Moab is cut off, and his arm is broken, saith the LORD.
(n) That is, his power and strength.

The horn of Moab is cut off,.... The kingdom of Moab, high and strong, his power and strength, by which he defended himself, and offended others, as a beast with his horns; his powerful kingdom, and the glory of it:
and his arm is broken, saith the Lord; so that he cannot hold a sword, or manage any weapon of war against the enemy, or do anything to annoy him, or in his own defence. The Targum is,
"the kingdom of Moab is cut off, and their rulers are broken, saith the Lord;''
and so Ben Melech interprets it of his princes, and his armies, which were the arm of the king, and of the people.

horn--the emblem of strength and sovereignty: it is the horned animal's means of offense and defense (Psalm 75:5, Psalm 75:10; Lamentations 2:3).

The horn - That is the beauty and the strength of Moab.
