1 Clement

For so it is written, And it came to pass after certain days that Cain brought of the fruits of the earth a sacrifice unto God, and Abel he also brought of the firstlings of the sheep and of their fatness.

Γέγραπται γὰρ οὕτως: Καὶ ἐγένετο μεθ̓ ἡμέρας, ἤνεγκεν Κάϊν ἀπὸ τῶν καρπῶν τῆς γῆς θυσίαν τῷ θεῷ, καὶ Ἄβελ ἤνεγκεν καὶ αὐτὸς ἀπὸ τῶν πρωτοτόκων τῶν προβάτων καὶ ἀπὸ τῶν στεάτων αὐτῶν.

And God looked upon Abel and upon his gifts, but unto Cain and unto his sacrifices He gave no heed.

καὶ ἐπεῖδεν ὁ θεὸς ἐπὶ Ἄβελ καὶ ἐπὶ τοῖς δώροις αὐτοῦ, ἐπὶ δὲ Κάϊν καὶ ἐπὶ ταῖς θυσίαις αὐτοῦ οὐ προσέσχεν.
