Bel crouches; Nebo cowers. Their idols weigh down beasts and cattle. The images you carry are burdensome, a load to the weary animal.
KJV
Bel boweth down, Nebo stoopeth, their idols were upon the beasts, and upon the cattle: your carriages [were] heavy loaden; [they are] a burden to the weary [beast].
ASV
Bel boweth down, Nebo stoopeth; their idols are upon the beasts, and upon the cattle: the things that ye carried about are made a load, a burden to the weary beast.
