LXX Num 7:87

πᾶσαι αἱ βόες αἱ εἰς ὁλοκαύτωσιν μόσχοι ιβ΄, κριοὶ δώδεκα, ἀμνοὶ ἐνιαύσιοι ιβ΄, καὶ αἱ θυσίαι αὐτῶν καὶ αἱ σπονδαὶ αὐτῶν· καὶ χίμαροι ἐξ αἰγῶν δώδεκα περὶ ἁμαρτίας.

All the livestock for the burnt offering totaled twelve bulls, twelve rams, and twelve male lambs a year old—together with their grain offerings—and twelve male goats for the sin offering.
