Deuteronomy 4:3 Meaning and Commentary

Deuteronomy 4:3

Your eyes have seen what the Lord did because of Baalpeor,
&c.] Because of the idolatry the people of Israel fell into by worshipping that idol, being drawn into it by the daughters of Moab and Midian, through the counsel of Balaam, with whom they committed fornication; which led them to the other sin, and both highly provoking to God. The Targums of Onkelos and Jonathan are,

``what the Word of the Lord has done to the worshippers of the idol Peor;''

for all the men that followed Baalpeor, the Lord thy God hath
destroyed them from among you;
24,000 persons died on that account; which being a recent thing, fresh in memory, and what they were eyewitnesses of, was a caution to them to avoid the same sins, as it is to us on whom the ends of the world are come, ( Numbers 23:9 ) ( 1 Corinthians 10:6-8 1 Corinthians 10:11 ) .

Deuteronomy 4:3 In-Context

1 And now, Israel, hear the ordinances and judgments, all that I teach you this day to do: that ye may live, and be multiplied, and that ye may go in and inherit the land, which the Lord God of your fathers gives you.
2 Ye shall not add to the word which I command you, and ye shall not take from it: keep the commandments of the Lord our God, all that I command you this day.
3 Your eyes have seen all that the Lord our God did in Beel-phegor; for every man that went after Beel-phegor, the Lord your God has utterly destroyed him from among you.
4 But ye that kept close to the Lord your God are all alive to-day.
5 Behold, I have shewn you ordinances and judgments as the Lord commanded me, that ye should do so in the land into which ye go to inherit it.
