And hath not eaten {b} upon the mountains, neither hath lifted up his eyes to the idols of the house of Israel, neither hath defiled his neighbour's wife, neither hath come near to a polluted woman,

(b) If he has not eaten flesh that has been offered up to idols, to honour them by it.

Wesley's Notes

18:6 Hath not eaten - Hath not committed idolatry, offering sacrifice, and eating of the things sacrificed to idols; whose temples and altars were on mountains, chap. 20. and 28. Hos 4:13.

Jamieson-Fausset-Brown Bible Commentary

6. not eaten upon . mountains-the high places, where altars were reared. A double sin: sacrificing elsewhere than at the temple, where only God sanctioned sacrifice (De 12:13, 14); and this to idols instead of to Jehovah. "Eaten" refers to the feasts which were connected with the sacrifices (see Ex 32:6; De 32:38; Jud 9:27; 1Co 8:4, 10; 10:7).

lifted . eyes to-namely, in adoration (Ps 121:1). The superstitious are compared to harlots; their eyes go eagerly after spiritual lusts. The righteous man not merely refrains from the act, but from the glance of spiritual lust (Job 31:1; Mt 5:28).

idols of . Israel-not merely those of the Gentiles, but even those of Israel. The fashions of his countrymen could not lead him astray.

defiled . neighbour's wife-Not only does he shrink from spiritual, but also from carnal, adultery (compare 1Co 6:18).

neither . menstruous woman-Leprosy and elephantiasis were said to be the fruit of such a connection [Jerome]. Chastity is to be observed even towards one's own wife (Le 18:19; 20:18).

Matthew Henry's Concise Commentary

18:1-20 The soul that sinneth it shall die. As to eternity, every man was, is, and will be dealt with, as his conduct shows him to have been under the old covenant of works, or the new covenant of grace. Whatever outward sufferings come upon men through the sins of others, they deserve for their own sins all they suffer; and the Lord overrules every event for the eternal good of believers. All souls are in the hand of the great Creator: he will deal with them in justice or mercy; nor will any perish for the sins of another, who is not in some sense worthy of death for his own. We all have sinned, and our souls must be lost, if God deal with us according to his holy law; but we are invited to come to Christ. If a man who had shown his faith by his works, had a wicked son, whose character and conduct were the reverse of his parent's, could it be expected he should escape the Divine vengeance on account of his father's piety? Surely not. And should a wicked man have a son who walked before God as righteous, this man would not perish for his father's sins. If the son was not free from evils in this life, still he should be partaker of salvation. The question here is not about the meritorious ground of justification, but about the Lord's dealings with the righteous and the wicked.
