v.11
An image from nature compares unjust enrichment to a bird that broods over eggs it did not produce. The point is the mismatch between possession and rightful origin: wealth gained “not by right” proves temporary and ends in public disgrace.
v.12
A counter-image emphasizes permanence: a “glorious throne” set on high “from the beginning,” linked with “the place of our sanctuary.” The verse functions as a stabilizing reference point over against fleeting gain.
v.13
Direct address names Yahweh as Israel’s hope and states outcomes: those who forsake him are put to shame, and those who depart are “written in the earth,” suggesting a memory that does not last. The metaphor of “living” waters underscores the social consequence of severing ties with the true source of life (cf. Jeremiah 2:13).
