ירמיהו, פרק ט׳, פסוק כ״ה

A sweeping judgment approaches, targeting a specific lineup of nations and kingdoms destined to fall to the Babylonian Empire under King Nebuchadnezzar [מצודת דוד]. Placing the kingdom of Judah in the exact same category as its foreign neighbors points to a profound spiritual collapse. It sends a clear message that external symbols of a covenant offer no protection to those who abandon God's path. These targeted nations were neighbors of the Land of Israel and faced their punishment around the same time as Judah's destruction [רש״י]. The northern kingdom of Israel is absent from this impending doom simply because it had already been destroyed earlier by the king of Assyria [רד״ק].

The destruction reaches even the most isolated desert dwellers. The primary approach among commentators understands these groups geographically and socially, identifying them as scattered, disconnected tribes living at the far edges of the desert, such as the kingdoms of Kedar and Hazor [רש״י, מצודת דוד, מצודת ציון, רד״ק]. Others view their unique description through a cultural lens, noting that these desert tribes were recognized by their practice of shaving or cutting the corners of their hair and beards [ביאור שטיינזלץ]. Another perspective links them to their ancestry and religion, identifying them as descendants of Ishmael and Keturah who were known to physically circumcise themselves [מלבי״ם].

The shared fate of Judah and its neighbors stems from a stark comparison between them. The foreign nations are characterized as uncircumcised, regardless of whether they actually practiced physical circumcision or not [ביאור שטיינזלץ]. They are not being punished for this status, as God never commanded them to perform the act; rather, this detail is highlighted solely to emphasize the tragic reality of the Israelites [רד״ק]. While the Israelites carry the physical mark, their disgrace is entirely internal. Their hearts are blocked, sealed, and covered as if wrapped in a thick layer of fat [מצודת ציון, ביאור שטיינזלץ].

Physical circumcision was intended to serve as the mark of an eternal covenant, setting the Israelites apart from the rest of the world so they could serve God. However, by blending in with the surrounding nations and adopting their behaviors, the Israelites allowed their hearts to become sealed, effectively breaking the covenant completely. In this compromised spiritual state, the physical mark on their flesh loses all meaning and provides no defense. As a result, they are judged and punished exactly like the foreign nations around them [רד״ק].
