Though (ei kai). Not kai ei (even if). Yet (alla). Common use of alla in the apodosis (conclusion) of a conditional or concessive sentence. Your order (thn taxin). The military line (from tassw), unbroken, intact. A few stragglers had gone over to the Gnostics, but there had been no panic, no breach in the line. Steadfastness (sterewma). From stereow (from stereo) to make steady, and probably the same military metaphor as in taxin just before. The solid part of the line which can and does stand the attack of the Gnostics. See Acts 16:5 where the verb stereow is used with pisti and 1 Peter 5:9 where the adjective stereo is so used. In 2 Thessalonians 3:62 Thessalonians 3:82 Thessalonians 3:11 Paul speaks of his own taxi (orderly conduct).
