Poplar—i.e., the white poplar, not the storax of the LXX., which is a shrub only a few feet high.

Elms should be “terebinth tree” (’ēlah).

Being thus connected with idolatry and sin, God strictly forbade the worship on the high places, and (as is the case with so many of God's commandments) man practiced it as diligently as if He had commanded it. God had said, "Ye shall utterly destroy all the places, wherein the nations, which ye shall possess, served their gods upon the high mountains, and upon the hills and under every green tree" Deuteronomy 12:2. But "they set them up images and groves (rather images of Ashtaroth) in every high hill and under every green tree, and there they burnt incense in all the high place, as did the pagan whom the Lord carried away before them" 2 Kings 17:10-11. The words express, that this which God forbade they did diligently; "they sacrificed much and diligently; they burned incense much and diligently" ; and that, not here and there, but generally, "on the tops of the mountains," and, as it were, in the open face of heaven. So also Ezekiel complains, "They saw every high hill and all the thick trees, and they offered there their sacrifices, and there they presented the provocation of their offering; there also they made their sweet savor, and poured out there their drink-offerings" Ezekiel 20:28.

Under oaks - (white) poplars and elms (probably the terebinth or turpentine tree) because the shadow thereof is good The darkness of the shadow suited alike the cruel and the profligate deeds which were done in honor of their false gods. In the open face of day, and in secret they carried on their sin.

Therefore their daughters shall commit whoredoms, and their spouses - (or more probably, daughters-in-law) shall commit adultery Or (in the present) commit adultery. The fathers and husbands gave themselves to the abominable rites of Baal-peor and Ashtaroth, and so the daughters and daughters-in-law followed their example. This was by the permission of God, who, since they "glorified not" God as they ought, "gave them up," abandoned them, "to vile affections." So, through their own disgrace and bitter griefs, in the persons of those whose honor they most cherished, they should learn how ill they themselves had done, in departing from Him who is the Father and Husband of every soul. The sins of the fathers descend very often to the children, both in the way of nature, that the children inherit strong temptations to their parents' sin, and by way of example, that they greedily imitate, often exaggerate, them. Wouldest thou not have children, which thou wouldest wish unborn, reform thyself. The saying may include too sufferings at the hands of the enemy. "What thou dost willingly, that shall your daughters and your daughters-in-law suffer against thine and their will."

elms—rather, "terebinths" [Maurer].

shadow … good—screening the lascivious worshippers from the heat of the sun.

daughters … commit whoredom … spouses … adultery—in the polluted worship of Astarte, the Phœnician goddess of love.

and burn incense upon the hills; to their idols, which was one kind of sacrifice put for all others:

under oaks, and poplars, and elms; and indeed under every green tree that grew upon them, where there were groves of them raised up for this purpose; see Jeremiah 2:20,

because the shadow, thereof is good; the shadow of these trees, of each of them, was large, and preserved them from the sultry heat of the sun, as well as hid them from the sight of men; they could perform their idolatrous rites, as well as gratify their impure lusts, with more privacy and secrecy; and perhaps they thought the gods delighted in such shady places, and that these were frequented by spirits, and the departed souls of men; in such places the Heathens, whom the Jews imitated, built their temples, and offered their sacrifices (g). The "oak" is a very spreading tree; its branches are large, and its shadow very great: hence the religious Heathens in ancient times used to live under them, and worship them as gods, and dedicate temples to them, because they furnished them with acorns for food, and a shelter from the rain, and other inclemencies of the heavens (h); particularly the oak was consecrated to Jupiter, as appears from what Virgil says (i). The oak at Dodona is famous for its antiquity, where were a fountain and groves, and a temple dedicated to the same Heathen deity; and from whence oracles were given forth (k). The Druids here in Britain chose to have their groves of oaks; nor did they perform any of their sacred rites without the leaves of them: hence Pliny (l) says they had their name. The "poplar" mentioned is the white poplar, as the word used signifies, and which affords a very hospitable shadow, as the poet (m) calls it; and this was a tree also with the Heathens sacred to their gods, particularly to Hercules (n); because it is said he brought it first into Greece from the river Acheron, where it grew; and the wood of no other tree would the Eleans use, in preparing the sacrifices for Jupiter Olympius (o). The "elm" is also a very shady tree; hence Virgil (p) calls it "ulmus opaca, ingens": and under this tree sacrifices used to be offered to idols, as is evident from Ezekiel 6:13, where the same word is used as here, though it is there rendered an "oak"; but that it is different from the oak appears from these two words being read together, so that they cannot be names of one and the same tree, Isaiah 6:13, where it is rendered the "teil tree", as distinct from the oak. Now these trees being very shady ones, and under which the Gentiles used to perform their religious rites, the Jews imitated them therein, which is here complained of.

Therefore your daughters shall commit whoredoms, and your spouses shall commit adultery; or their "sons' wives" (q); either spiritually, that is, commit idolatry by the example of their parents and husbands; or corporeally, being left at home while their parents and husbands were worshipping their idols upon the mountains, as Aben Ezra and Kimchi: and so this is to be considered as a punishment of the idolatry of their parents and husbands; that as they commit spiritual adultery against God, or idolatry, their daughters and wives shall be given up to such vile affections, or by force shall be made to commit corporeal adultery against them; or rather the sense is, led by the example of their parents and husbands, whom they see not only sacrifice to idols in the above places, but commit uncleanness with harlots there, they will throw off all shame, and commit whoredom with men: for so the words may be rendered, "hence your daughters", &c.; so Abarbinel.
