LXX Num 15:25

καὶ ἐξιλάσεται περὶ αὐτοῦ ὁ ἱερεύς, περὶ πάσης συναγωγῆς υἱῶν Ἰσραὴλ, καὶ ἀφεθήσεται αὐτοῖς· ὅτι ἀκούσιόν ἐστιν· καὶ αὐτοὶ ἤνεγκαν τὸ δῶρον αὐτῶν κάρπωμα Κυρίῳ περὶ τῆς ἁμαρτίας αὐτῶν ἔναντι κυρίου περὶ τῶν ἀκουσίων αὐτῶν.

The priest is to make atonement for the whole congregation of Israel, so that they may be forgiven; for the sin was unintentional and they have brought to the LORD an offering made by fire and a sin offering, presented before the LORD for their unintentional sin.
