They sacrifice on the tops of the mountains, And burn incense on the hills, under oaks and poplars and terebinths, Because its shade is good. Therefore your daughters play the prostitute, And your brides commit adultery.
The Prophet also distinctly excludes a device in which the ungodly and hypocrites take great delight: good, he says, was its shade; that is, they pleased themselves with such devices. So Paul says that there is a show of wisdom in the inventions and ordinances of men, (Colossians 2:23.) Hence, when men undertake voluntary acts of worship, — which the Greeks call εθελοθρησκείας superstitions, being nothing else than will-worship, — when men undertake this or that to do honor to God, there appears to them a show of wisdom, but before God it is abomination only. At this practice the Prophet evidently glances, when he says that the shade of the poplar, or of the oak, or of teil-tree, was good; for the ungodly and the hypocrites imagined their worship to be approved of God, and that they surpassed the Jews, who worshipped God only in one place: “Our land is full of altars, and memorials of God present themselves everywhere.” But when they thought that they had gained the highest glory by their many altars, the Prophet says, that the shade indeed was good, but that it only pleased wantons, who would not acknowledge their baseness.
