Jeremiah comes now, I think, to the second table, and mentions one kind of evil; but his object was to shew that there was no chastity, no faithfulness, no honesty in that people. He therefore compares them to wanton and lustful horses, and thus exposes their infamous conduct. Had he said that every one did lie in wait for the bed of his neighbor, it would have been a heinous crime; but when he calls their lust neighing, and calls them horses, and those well fed, and who rise early after they are filled, he doubtless shews that such was their incontinence, that they were not only wanton and adulterous, but that they were worse and more base, for they differed nothing from lustful horses, and horses well fed. Some read the last word "armed, "deducing it from yvnizan, which means to be armed; and others derive it from zvn, zun, which signifies to eat, and hence they take mvzn, muzan, for food. There is indeed no doubt but that it means here "fed, "or fat; for why should he call them armed horses? What some say, that they rose early after having committed adultery, in order to exhibit their disgrace, and to boast of their vices, is too far-fetched. What is meant is, that they were strong horses, and active, and that they rose up early after having been well fed. [1] We now then understand the Prophet's object: the sum of the whole is, -- that there was no chastity among the Jews, for they gave themselves up to wanton lusts, not only like adulterers and whoremongers, but like lascivious horses. Nevertheless, as we have said, he includes here, under incontinency, thefts, frauds, rapines, and all vices of this kind; for he no doubt charges the Jews as guilty of transgressing against the second table of the law. He afterwards adds --

Footnotes

1 - The literal rendering of this verse, and countenanced by ancient versions, is as follows, -- Horses well fed! libidinous have they become; They neigh, every one at the wife of his neighbor. Both Venema and Blayney agree in giving this meaning. It does not seem, when the whole context is viewed, that adultery here is to be taken in its literal sense. It is spiritual adultery, that is, idolatry, that is referred to throughout the chapter. Besides, the comparison in this verse is such, that its application is more suitable to idolatrous acts than to those which are adulterous. The same may be said of what is found in the preceding verse, -- that they crowded the house of the harlot. This is not so much the case in adultery as in idolatry, when people fill their idolatrous temples. A simile is sometimes carried beyond what is actually the case, in order to convey a right idea of what it is intended to illustrate. When they are said to be like well-fed stallions, and neighing at the wives of their neighbors, the purpose was to shew with what intense ardor they were devoted to idolatry: and the degrading comparison was no doubt made in order to pour contempt on their mad propensity: it was like the impetuous instinct of an animal, uncontrolled by any reason, persuasion, or remonstrance. -- Ed.

In the morning - Render, they rove about. Some prefer, "(horses) from Mesech."

After his neighbor's wife - This may have been literally true, as the abominations of idolatry, in which they were so deeply practiced, would necessarily produce such a state of things as that here mentioned.

They were as fed horses in the morning,.... Adulterers are compared to horses, because they are very salacious and lustful creatures; wherefore the Septuagint renders the word: "horses are become mad after the females"; or, "as horses mad after the females are they become"; and especially to such as are well kept and are fat, and who, having much food given them in the night, and being full in the morning, go forth neighing, as Kimchi observes; and are the more salacious in the morning, by being so well fed all night, as those persons were, as is expressed in the preceding verse; though some render the word translated "in the morning", (for which sense of it see Hosea 6:4) "drawing out" (u); that is, the genital member, as lascivious horses do. The word is difficult of interpretation. The Targum calls them field or wood horses; horses that run in fields and woods, and are very vicious and wanton:,
everyone neighed after his neighbour's wife; coveted and lusted after her, signified his lustful desires, and sought an opportunity to defile her. Neighing is a sign of lust, and keeps up the metaphor of the horse.
(u) "trahentes", Aquila, Symmachus & Theodotion in Bootius, l. 3. c. 5. sect. 3. Aben Ezra and Abendana interpret it of horses that come from Meshec; see Psal. cxx. 5. which were the strongest and most lascivious.

in the morning-- (Isaiah 5:11). "Rising early in the morning" is a phrase for unceasing eagerness in any pursuit; such was the Jews' avidity after idol-worship. MAURER translates from a different Hebrew root, "continually wander to and fro," inflamed with lust (Jeremiah 2:23). But English Version is simpler (compare Jeremiah 13:27; Ezekiel 22:11).
