The textbook reads καὶ οὐκ ἐγίνωσκεναὐτὴνἕως οὗ ἔτεκενυἱόν.1 But Matthew 1:25 in UBS5 reads καὶ οὐκ ἐγίνωσκεναὐτὴν ἕως οὗ ἔτεκεν υἱόν
The textbook reads καὶ ἀπέστειλεν πρὸς τοὺς γεωργοὺς τῷ καιρῷδοῦλον (Mark 12:2)1 But mark 12:2 in UBS5 actually reads καὶ ἀπέστειλεν πρὸς τοὺς γεωργοὺς τῷ καιρῷ δοῦλον
The textbook reads ἵνα στρατεύῃ ἐν αὐταῖς τὴν καλὴνστρατείαν But 1 Timothy 1:18 in UBS5 actually reads ἵνα στρατεύῃ ἐναὐταῖς τὴν καλὴν στρατείαν
Three very sloppy editing errors in a single paragraph! If these were isolated errors, I would simply submit a typo and read on, but I have seen other such errors, and I am only in chapter 2. Surely a spellchecker would detect such errors.
