'Saying' in the Bible

Now I mean this, that each of you is saying, "I am with Paul," or "I am with Apollos," or "I am with Cephas," or "I am with Christ."

I am saying this for your benefit, not to place a limitation on you, but so that without distraction you may give notable and constant service to the Lord.

Am I saying these things only on the basis of common sense, or does the law not say this as well?

Am I saying that idols or food sacrificed to them amount to anything?

In the same way, he also took the cup after supper, saying, "This cup is the new covenant in my blood. Do this, every time you drink it, in remembrance of me."

Otherwise, if you are praising God with your spirit, how can someone without the gift say "Amen" to your thanksgiving, since he does not know what you are saying?

Now this is what I am saying, brothers and sisters: Flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable.

Now when this perishable puts on the imperishable, and this mortal puts on immortality, then the saying that is written will happen, "Death has been swallowed up in victory."
