A stern warning of approaching punishment is directed at a corrupt ruling class and their eager servants. God promises to bring justice upon those who leap over the doorway threshold [ביאור שטיינזלץ, מצודת ציון]. This striking image points to a deep spiritual betrayal, representing the adoption of foreign religious customs. The behavior mimics the Philistine worship of Dagon, where priests carefully avoided stepping on the entranceways of their temples [רש״י, רד״ק, אברבנאל, ביאור שטיינזלץ]. In a tragic irony, the Israelites took this idolatrous practice even more seriously than the foreign nations who invented it [רד״ק].
Beyond foreign worship, the plain meaning of this frantic leaping points directly to government corruption and unchecked greed [אברבנאל]. It describes the hurried movements of royal servants, officials, and enforcers who rush to seize property. Commentators offer different perspectives on exactly whose doorways these corrupt officials are jumping over. One approach suggests they are leaping over the thresholds of the poor and common people, driven by a hasty, ruthless desire to steal and oppress [מצודת דוד, רד״ק]. Another perspective explains that the doorway belongs to the palaces of the kings and ministers themselves. Driven by a desperate eagerness to please their masters, these servants bound into the royal estates, thrilled to deliver their stolen goods [אבן עזרא, רד״ק, אברבנאל].
These two distinct themes of idolatry and corruption can also be viewed as one cohesive metaphor. Just as the Philistine priests leaped in awe at their temples, the royal servants leap with fearful reverence and enthusiasm at the doors of their corrupt masters [מלבי״ם]. Ultimately, all these frantic efforts serve a single, dark purpose: filling the homes of those who sent them with vast wealth amassed entirely through violence, robbery, and fraud [מצודת ציון, מצודת דוד, ביאור שטיינזלץ].
