Deuteronomy 20:18

That they teach you not to do after all their abominations, which they have done unto their gods; so should ye sin against the Lord your God.

Deuteronomy 20:18 (KJV)

Context

Deuteronomy records Moses’ speeches to Israel before they entered the Promised Land. In this chapter, Moses gives rules for warfare, telling Israel how to act when they fight their enemies. The command to destroy the Canaanite nations was part of God’s plan as His people prepared to possess the land.

Meaning

The verse names the reason for the command to destroy the Canaanite nations. They must not teach Israel to copy their abominations, which were practices connected to the worship of false gods and detestable to the Lord. If Israel learned these ways, they would sin against God. The warning shows that sin can be learned from others, and that God’s commands protect His people from spiritual corruption. The central concern is the danger of influence—that the ungodly practices of surrounding nations would corrupt God’s people. This was not merely a military strategy but a spiritual safeguard.

Biblical connections

God wanted Israel to be set apart, holy, and obedient to Him. Their separation from these nations was for spiritual preservation, not just military safety. The abominations included idolatrous worship and associated practices that were an abomination to God. The verse shows that sin is not only personal but can be learned from others, and that God’s commands are designed to protect His people from spiritual corruption.

Application

Though this verse addresses Israel in the Promised Land, its principle applies to believers today. As Christians, we are called to be separate from the world’s values and practices (Romans 12:2). We should not conform to ungodly patterns but live by God’s standards. This verse reminds us to guard our hearts and minds against harmful influences. We must be discerning about what we allow into our lives and seek to align with God’s truth. The principle extends to believers today: we must guard against influences that would lead us away from wholehearted devotion to God.

Reflection

God’s holiness and His desire for His people to be distinct from the nations are clear here. The command was not harsh without purpose; it was a protective measure. Sin is serious, and avoiding it may require decisive action. We should examine the influences around us and ask whether they draw us closer to God or lead us away from wholehearted devotion to Him. The verse calls us to remain faithful, avoiding the abominable practices of the world and continually seeking to live according to His will.
