Job 41:2

Canst thou put a hook into his nose -Or rather, a “rope,” or “cord.” The word used here (אגמון'agmôn) means “a caldron,” or “kettle”Job 41:20, also a reed, or bulrush, growing in marshy places, and thus a rope made of reeds, a rush-cord. The idea is, that he could not be led about by a cord, as tame animals may be. Mr. Vansittart, however, supposes that the words here are expressive of ornaments, and that the allusion is to the fact mentioned by Herodotus, that the crocodile was led about by the Egyptians as a divinity, and that in this state it was adorned with rings and various stately trappings.
