Rashi
Bel squats; Nebo soils himself The deities of Babylon squatted and soiled themselves. This is an expression of ridicule of the idols, like one who suffers from diarrhea and does not manage to sit down on the seat in the privy before he discharges with a splash.
Ibn Ezra
Bel. The idol of the Babylonians; the same is the case with Nebo. The latter is explained by some to signify the sun.
Rashi
Bel squats; Nebo soils himself Heb. כָּרַע בֵּל קֹרֵס נְבוֹ. Akropid sei Bel; konkiad sei Nebo. Bel squats; Nebo soils himself. So I heard in the name of Rabbenu Gershom, the Light of the Diaspora.
Rashi
their idols were The images of the forms of Bel and Nebo were to the beasts and the cattle, compared to the beasts and the cattle, which soil and dirty themselves with their droppings.
Rashi
what you carry is made a load, a burden The feces in their bowels are heavy to bear like a burden for a weary man. Therefore, they soiled themselves and squatted together, the soiling with the squatting.
