'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?

For, in fact, that which was once resplendent in glory has no glory at all in this respect, that it pales before the glory which surpasses it.

Three times I have been beaten with Roman rods, once I have been stoned, three times I have been shipwrecked, once for full four and twenty hours I was floating on the open sea.
