LXX Num 32:13

καὶ ὠργίσθη θυμῷ κύριος ἐπὶ τὸν ᾿Ισραήλ, καὶ κατερόμβευσεν αὐτοὺς ἐν τῆ ἐρήμῳ τεσσεράκοντα ἔτη, ἕως ἐξανηλώθη πᾶσα ἡ γενεά, οἱ ποιοῦντες τὰ πονηρὰ ἔναντι κυρίου.

The anger of the LORD burned against Israel, and He made them wander in the wilderness forty years, until the whole generation who had done evil in His sight was gone.
