Following the destruction of the Temple, a small group of survivors remained in the land of Israel, taking shelter among ruined cities and caves. Despite the devastation around them, these individuals held onto a strong belief that the holiness of the land remained intact and that they were destined to maintain possession of it.
They built their confidence on a historical and demographic comparison to Abraham. They reasoned that Abraham was just a single individual, yet he merited to inherit the entire land. In contrast, even though their numbers were vastly diminished compared to the population before the destruction, they were still a large group compared to one man. Therefore, they concluded that the land rightfully belonged to them as an inheritance. In their eyes, the simple fact that they had survived the war was clear proof of God's favor, making them the natural heirs to the properties left behind by those who had perished [מצודת דוד, ביאור שטיינזלץ].
Some expand on the depth of this claim, noting that beyond the advantage of numbers, the survivors felt their hold on the land was more secure than Abraham's. While Abraham only received a future promise of the land, they possessed a land that had already been given to them in the past [מלבי״ם]. Another perspective suggests they leaned heavily on God's original promise to the forefathers. According to this view, Abraham did not take practical ownership of the land during his lifetime in order to preserve that right for his future descendants. Now that these survivors represented his multiplied offspring, they demanded the realization of that promise in Abraham's place, regardless of whether their own actions made them worthy [חומת אנך].
In the teachings of the early sages, the contrast between the single individual and the larger group is viewed through a spiritual lens rather than a strictly numerical one. One approach explains that the survivors argued Abraham fulfilled only a single Commandment and was rewarded with the land, whereas they were obligated to fulfill many Commandments, making their claim even stronger [רש״י ורד״ק בשם רשב״י]. Conversely, a more cynical interpretation suggests that these sinful survivors actually boasted about their idolatry. They claimed that since Abraham worshipped only one God and inherited the land, their practice of worshipping many gods would certainly guarantee their inheritance [רד״ק בשם רבי עקיבא].
Ultimately, this deep sense of security was nothing more than an illusion. The prophet prepares to dismantle their arguments, making it clear that the protective merit of the forefathers had already been exhausted during the era of the First Temple. Now, as a direct result of their severe sins, the land is destined to become an absolute wasteland, entirely stripped of its former holiness [מלבי״ם, רד״ק, חומת אנך].
