NET
1 Bel kneels down, Nebo bends low. Their images weigh down animals and beasts. Your heavy images are burdensome to tired animals.
Darby
1 Bel is bowed down, Nebo bendeth; their idols are upon the beasts, and upon the cattle: the things ye carried are laid on, a burden to the weary [beast].
KJV
1 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].
