Verse 134

وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُوا۟ يَـٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٰٓءِيلَ

And each time adversity befell them, they said; O Moses, call upon your Lord on our behalf, according to the covenant He has with you, to remove this adversity from us and we will surely believe for your sake and we will indeed let the Children of Israel go with you.
