'Once' in the Bible

maintaining, as you do, the same kind of conflict that you once saw in me and which you still hear that I am engaged in.

Therefore I hope to send him at once, as soon as I see {my circumstances}.

although I once also had confidence in the flesh. If anyone else thinks he has grounds for confidence in the flesh, I have more:

Now I rejoice in the Lord greatly, because once again you have shown your concern for me. Of course, you were concerned for me but you did not have an opportunity to show it.

For even in Thessalonica ye sent once and again unto my necessity.
