LXX Deut 10:10

κἀγὼ ἱστήκειν ἐν τῷ ὄρει τεσσεράκοντα ἡμέρας κα τεσσεράκοντα νύκτας, καὶ ἤκουσεν Κύριος ἐμοῦ καὶ ἐν τῷ καιρῷ τούτῳ, καὶ οὐκ ἠθέλησεν κύριος ἐξολεθρεῦσαι ὑμᾶς.

I stayed on the mountain forty days and forty nights, like the first time, and that time the LORD again listened to me and agreed not to destroy you.
