1 The god did grant his daughter's dear demand,
dear > earnest; expensive
2 To do his nephew in all riches flow;
do > make nephew > grandson
3 Eftsoons his heaped waves he did command
Eftsoons > Soon; thereupon
4 Out of their hollow bosom forth to throw 5 All the huge treasure, which the sea below 6 Had in its greedy gulf devoured deep,
gulf > abyss
7 And him enriched through the overthrow
him > itself (if referring to the sea); him (if referring to Nereus)
