And it shall be, if thou do at all forget the LORD thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish.
This verse presents covenant curse for forgetting God and pursuing idolatry. The conditional 'if thou do at all forget' uses emphatic Hebrew construction (shakhoach tishkach) meaning 'surely forget' or 'completely forget.' Walking after, serving, and worshiping other gods represents comprehensive apostasy—progressive departure from mild neglect to active idolatry. The phrase 'I testify against you this day' (ha'idoti) is legal language—Moses serves as witness in a covenant lawsuit. The consequence is unequivocal: 'ye shall surely perish' (avod toveidun, emphatic construction meaning certain destruction). This isn't arbitrary punishment but covenant justice—violation brings curse as surely as obedience brings blessing (Deuteronomy 28).
Historical Context
This warning proved prophetic. The northern kingdom's persistent Baal worship led to Assyrian conquest and exile (722 BC, 2 Kings 17:7-23). Judah's apostasy resulted in Babylonian captivity (586 BC, 2 Chronicles 36:15-21). Both destructions fulfilled this warning exactly—they forgot the LORD, walked after other gods, and perished as nations. The prophets (Jeremiah, Ezekiel, Hosea) repeatedly invoked covenant curses, warning that idolatry would bring the threatened destruction. Israel's history demonstrates that God's warnings are not empty threats but certain prophecies.
