Valmiki Ramayana Yuddha Kanda Sarga 119 Shloka 26

शुद्धचरिताम् unimpeachable conduct, माम् me, राघवः Raghava, दुष्टाम् seeing, जानाति not know, यथा similarly, तथा that way, लोकस्य world, साक्षी witness, पावकः fire, सर्वतः all sides, माम् me, पातु protect me

"If in Rama's view, I am of impeccable conduct and so also if what he is seeing is not known to be true, let the world witness and fire god protect me."
