Matthew Poole and continuators on Job 41:2

2. Canst thou put an hook into his nose ? or bore his jaw through with a thorn .

Heb. a Bulrush, i. e. an Hook like a Bulrush with its head hanging down, as is expressed, Isa. 58. 5.

To hang him up by it for Sale, or to carry him home for use, after thou hast drawn him out of the Sea or River, of which he spake in the former Verse.

Or, with an Iron Hook or Instrument as sharp as a Thorn: wherewith thou usest to carry little Fishes.
