תִּמְשֹׁ֣ךְ לִוְיָתָ֣ן בְּחַכָּ֑ה וּ֝בְחֶ֗בֶל תַּשְׁקִ֥יעַ לְשֹׁנֽוֹ׃
Canst thou draw out leviathan with a fish-hook? Or press down his tongue with a cord?
Rashi on Job
Can you pull the leviathan etc. When you pull him with a harpoon and insert a fishhook into his nose, will he offer much supplication to you? It means that you are unable to approach him with fishing implements.
Rashi on Job
or press down his tongue Let the rope down (on his tongue) to draw him out of his place.
