'Bless' in the Bible

and labour, working with our own hands; being reviled, we bless; being persecuted, we suffer;

The cup of the blessing that we bless -- is it not the fellowship of the blood of the Christ? the bread that we break -- is it not the fellowship of the body of the Christ?

since, if thou mayest bless with the spirit, he who is filling the place of the unlearned, how shall he say the Amen at thy giving of thanks, since what thou dost say he hath not known?
