Genesis 1:28 gives man dominion over creatures, but Leviathan cannot be subdued as a servant — highlighting the limit of that dominion.

Exodus 21:6 describes a servant who serves forever, directly paralleling the language of taking Leviathan as a servant forever — but Leviathan refuses.

Deuteronomy 15:17 repeats the same perpetual servitude law, contrasting with Leviathan who will not become a servant.

Psalm 8:6 says all things are under man's feet, yet Leviathan cannot be taken as a servant — a direct contrast.
