2 Timothy 2:23

τὰς δὲ μωρὰς καὶ�, but foolish and ignorant questionings refuse. The irrelevancy of much of the controversy then prevalent among Christians seems to have deeply impressed St Paul; again and again he returns to this charge against the heretical teachers, that their doctrines are unprofitable and vain, and that they breed strife about questions either unimportant or insoluble. See 1 Timothy 1:4; 1 Timothy 1:7; 1 Timothy 4:7; 1 Timothy 6:4; 1 Timothy 6:20; Titus 3:9 &c. The adj. ἀπαίδευτος (undisciplined, or untaught, and so ignorant) does not occur again in the N.T. For παραιτοῦ see on 1 Timothy 4:7.

εἰδὼς ὅτι γεννῶσιν μάχας, knowing that they gender strifes. A seemingly harmless speculation as to obscure problems of theology or sacred history may become directly injurious to true religion, if it issue in verbal controversies. Cp. 2 Timothy 2:14.
