'Once' in the Bible

Do you say that this is self-recommendation once more? Or do we need, as some do, letters of recommendation to you or from you?

In fact, that which once had glory lost its glory, because the other glory surpassed it.

So from now on we regard no one from a human point of view [according to worldly standards and values]. Though we have known Christ from a human point of view, now we no longer know Him in this way.

And we are ready to punish any disobedience, once your obedience has been confirmed.

For [you seem willing to allow it] if one comes and preaches another Jesus whom we have not preached, or if you receive a different spirit from the one you received, or a different gospel from the one you accepted. You tolerate all this beautifully [welcoming the deception].

Are they the Messiah's servants? I am insane to talk like this, but I am a far better one! I have been involved in far greater efforts, far more imprisonments, countless beatings, and have faced death more than once.

Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck, a night and a day I have been in the deep;

I am afraid that when I come my God may again humble me before you and that I may have to grieve over many who formerly lived in sin and have not repented of their impurity, sexual immorality, and promiscuity that they once practiced.
