A desperate mother places her trust in the kindness of the king, approaching him to prevent the total ruin of her family. She holds onto the hope that the king will listen to her pleas, deliver a just ruling in her favor, and actively intervene to save her [מלבי״ם, ביאור שטיינזלץ].
The immediate danger she faces comes from a blood avenger who is determined to kill her son [רש״י, מצודת דוד]. She views this looming tragedy as a shared destruction. For the son, the destruction is his literal physical death. For the mother, the destruction is the devastating reality of surviving only to be left bereaved and entirely childless [מצודת דוד].
This tragedy threatens to cut them off from God's inheritance, a loss that is understood in two distinct ways. It may refer to the danger of being forcibly uprooted from the physical land that heaven granted to them [מצודת דוד]. Alternatively, the idea of God's inheritance can be viewed as a metaphor for life itself, meaning the impending violence would sever them from the very gift of existence [ביאור שטיינזלץ].
