Whose valiant heart will never quail Although a thousand foes assail; King Daśaratha’s son, the grace And glory of Ikshváku’s race. Obedient to his father’s will He cleaves to sacred duty still.

In plain words: Hanuman describes Rama: he is brave even against a thousand enemies, the son of King Dasharatha, the pride of the Ikshvaku family, and he still follows his duty by obeying his father.
