משלי, פרק ו׳, פסוק כ״ח

Imagine attempting to stroll across a bed of glowing coals without suffering any harm. The obvious reality is that escaping injury is completely impossible; the feet will inevitably burn [מצודת ציון]. There is a careful distinction between this scenario and the imagery of scooping a blazing fire directly into one's chest. Walking on coals seems like a far less dangerous action. There is no open flame, and the person is not pressing the heat against their core, but merely stepping across it [מלבי״ם]. Yet, despite this contact being partial and fleeting, the outcome remains absolutely certain.

This imagery serves as a powerful metaphor for the dangers of approaching sin, particularly in the context of forbidden relationships. Walking across the coals represents casual contact or simply placing oneself in close proximity to temptation, rather than committing the actual offense. Just as it is impossible to step on hot coals without the heat searing the flesh, even the slightest inappropriate touch or closeness awakens destructive desires. This mere proximity acts like a spark, heating the heart and the body, burning within a person until it inevitably drives them to complete the sinful act [אלשיך].
