Valmiki Ramayana Kishkindha Kanda Sarga 31 Shloka 30

बाणशल्यस्फुरज्जिह्वः the iron nails fixed on the arrows as moving fangs, सायकासनभोगवान् bow as the snake, स्वतेजोविषसङ्घातः his own brightness as poison, पञ्चास्यः fivehooded, पन्नगः इव snake like.

His bow was like the hood of a snake,with the iron nails fixed on the tip of his arrows like moving fangs and his own brightness like the venom of the fivehooded snake.
