Sin that remains unchecked brings about self-destruction.
They slice off what is on the right hand but still are hungry, And they eat what is on the left hand but they are not satisfied; Each of them eats the flesh of his own arm. (v.20) In this striking image, the prophet Isaiah describes a people so consumed by strife and sin that they metaphorically devour themselves. Their actions on the “right hand” and the “left hand” show how, despite their desperate attempts to fill their emptiness, they remain spiritually starved. This behavior represents a profound collapse of community, where neighbors turn on one another in a spiral of hostility, bringing about their own ruin.
This grim portrait resonates with other passages in Scripture that likewise use the imagery of consuming one’s own flesh or cannibalizing one’s community to expose the self-destructive nature of sin. One commentary on a different portion of Isaiah uses similar language to portray how human wickedness can cause people to devour one another, underscoring that such depravity ultimately leads to mutual harm and breakdown of society. A similar warning appears in the New Testament, where the Apostle Paul cautions believers not to “bite and devour” one another, lest they be consumed themselves (Galatians 5:15), echoing Isaiah’s graphic depiction of desperate people turning inward in destructive ways.
In Isaiah’s time, the covenant people’s disobedience had eroded their moral foundations so severely that they fought among themselves, seeking satisfaction through harmful means. Isaiah’s words present a pointed reminder that sin warps human relationships, leaving its victims forever hungry, never finding the peace and fulfillment that come only from faithfulness to the Lord. Ultimately, this passage reveals that God’s people need spiritual transformation and trust in Him, lest their own pursuits lead them to “eat the flesh of [their] own arm” in endless dissatisfaction.
