Numbers 25:1 While Israel lived in Shittim, the people began to whore with the daughters of Moab. These invited the people to the sacrifices of their gods, and the people ate and bowed down to their gods. So Israel yoked himself to Baal of Peor. And the anger of the Lord was kindled against Israel. And the Lord said to Moses, “Take all the chiefs of the people and hang them in the sun before the Lord, that the fierce anger of the Lord may turn away from Israel.” And Moses said to the judges of Israel, “Each of you kill those of his men who have yoked themselves to Baal of Peor.”
And behold, one of the people of Israel came and brought a Midianite woman to his family, in the sight of Moses and in the sight of the whole congregation of the people of Israel, while they were weeping in the entrance of the tent of meeting. When Phinehas the son of Eleazar, son of Aaron the priest, saw it, he rose and left the congregation and took a spear in his hand and went after the man of Israel into the chamber and pierced both of them, the man of Israel and the woman through her belly. Thus the plague on the people of Israel was stopped. Nevertheless, those who died by the plague were twenty-four thousand.
Exodus 34:14 (for you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God), lest you make a covenant with the inhabitants of the land, and when they whore after their gods and sacrifice to their gods and you are invited, you eat of his sacrifice, and you take of their daughters for your sons, and their daughters whore after their gods and make your sons whore after their gods.
Numbers 15:39 And it shall be a tassel for you to look at and remember all the commandments of the LORD, to do them, not to follow after your own heart and your own eyes, which you are inclined to whore after.
Deuteronomy 31:16 And the LORD said to Moses, “Behold, you are about to lie down with your fathers. Then this people will rise and whore after the foreign gods among them in the land that they are entering, and they will forsake me and break my covenant that I have made with them.
Judges 2:17 Yet they did not listen to their judges, for they whored after other gods and bowed down to them. They soon turned aside from the way in which their fathers had walked, who had obeyed the commandments of the LORD, and they did not do so.
Jeremiah 3:9 Because she took her whoredom lightly
Deuteronomy 29:19-21 one who, when he hears the words of this sworn covenant, blesses himself in his heart, saying, ‘I shall be safe, though I walk in the stubbornness of my heart.’ This will lead to the sweeping away of moist and dry alike. The LORD will not be willing to forgive him, but rather the anger of the LORD and his jealousy will smoke against that man, and the curses written in this book will settle upon him, and the LORD will blot out his name from under heaven.
The path away from God’s love, grace, and mercy – and straight into His anger and wrath is one of choice. Choosing to not only to do what seems right in their own heart and their own eyes and pleasing to them, but they do so thinking they are ok enough to be outside the disciplining hand of God. It does not take long for the weeds of deception to overtake the mind and soul of man. Neglect and complacent attitude with God’s word will give fertile soil for weeds of lies, deception, and false belief.
Matthew Henry commentary: The national covenant made with Israel, not only typified the covenant of grace made with true believers but also represented the outward dispensation of the gospel. Those who have been enabled to consent to the Lord’s new covenant of mercy and grace in Jesus Christ, and to give up themselves to be his people, should embrace every opportunity of renewing their open profession of relation to him, and their obligation to him, as the God of salvation, walking accordingly. The sinner is described as one whose heart turns away from his God; there the mischief begins, in the evil heart of unbelief, which inclines men to depart from the living God to dead idols. Even to this sin men are now tempted, when drawn aside by their own lusts and fancies. Such men are roots that bear gall and wormwood. They are weeds which, if let alone, overspread the whole field. Satan may for a time disguise this bitter morsel, so that thou shalt not have the natural taste of it, but at the last day, if not before, the true taste shall be discerned. Notice the sinner’s security in sin. Though he hears the words of the curse, yet even then he thinks himself safe from the wrath of God. There is scarcely a threatening in all the book of God more dreadful than this. Oh that presumptuous sinners would read it, and tremble! for it is a real declaration of the wrath of God, against ungodliness and unrighteousness of man.
