And hath not eaten upon the mountains,.... Where temples and altars were built for idols, and sacrifices offered up to them; and where feasts were kept to the honour of them, and the sacrifices to them eaten; see Eze 6:13; for otherwise it was not unlawful to eat common food on mountains, as well as on other places; but here it denotes idolatrous practices; and the Targum is, "and hath not served idols on the mountains:'' neither hath lifted up his eyes to the idols of the house of Israel; their "dunghill gods" (d) as the word signifies; as not to the idols of the Gentiles, so not to those of Israel, as the calves at Dan and Bethel; these he does not worship, nor pray unto, or invoke, nor even give a pleasant and favourable look unto; but turned from them with abhorrence and contempt: neither hath defiled his neighbour's wife; been guilty of adultery, by lying with another man's wife; or by marrying one divorced, not having committed fornication; which divorces were common among the Jews, and marrying such so divorced, Mat 19:19; neither hath come near to a menstruous woman: a woman in her monthly courses, even his own wife; who, according to the law, was set apart for her uncleanness for a certain term of time; during which she was not to be touched, nor anything she sat or lay upon; and all conjugal acts to be abstained from, Lev 15:19.
