While you, for strength and valour dread, The earth, like lordly lions, tread, Each bearing in his hand a bow, Like Indra’s own, to slay the foe. With the grand paces of a bull, So bright and young and beautiful.

In plain words: Hanuman praises the brothers as strong and brave, walking like lions and bulls. Each holds a bow like that of Indra, king of the gods.
