Valmiki Ramayana Ayodhya Kanda Sarga 77 Shloka 16

धर्मज्ञेन aware of righteous ways, महात्मना mighty, राज्ञा by the king, त्वया by you, या the earth, विहीना devoid of, पृथिवी that earth, अवदारणकाले at the time of breaking into pieces, नावदीर्यते does not break.

You are a righteous and mighty king and without you, this earth would have been broken into pieces. But it does not.
