LXX Deut 18:16

κατὰ πάντα ὅσα ᾐτήσω παρὰ κυρίου τοῦ θεοῦ σου ἐν Χωρὴβ τῇ ἡμέρᾳ τῆς ἐκκλησίας λέγοντες οὐ προσθήσομεν ἀκοῦσαι τὴν φωνὴν κυρίου τοῦ θεοῦ σου, καὶ τὸ πῦρ τὸ μέγα τοῦτο οὐκ ὀψόμεθα ἔτι, οὐδὲ μὴ ἀποθάνωμεν.

This is what you asked of the LORD your God at Horeb on the day of the assembly, when you said, “Let us not hear the voice of the LORD our God or see this great fire anymore, so that we will not die!”
