Valmiki Ramayana Yuddha Kanda Sarga 35 Shloka 15

सत् being good, लोकान् the worlds, चरता ranging, त्वया by you, महान् great, धर्मोऽपि even righteous conduct, विनिहतः giving up, अधर्मः unrighteous, प्रगृहीतश्च embraced by you, तेन therefore, परे enemy, अस्मत् more than you, बलिनः stronger.

"While you were ranging in all the worlds, you gave up righteousness and embraced unrighteousness. Therefore, the enemy who is righteous is stronger than you."
