Translation of "Renaîtrait" in English

A partir de cette soirée, Swann comprit que le sentiment qu'Odette avait eu pour lui ne renaîtrait jamais.

From that evening onwards, Swann understood that the feeling which Odette had once had for him would never revive.

" Contre un destin cruel que peut ce faible bras ? / Mon Hector même en vain renaîtrait de sa cendre. "

"Times so dire / not such defenders nor such help require. / Not e'en, were Hector here, my Hector's aid / could save us."
