'Saying' in the Bible

I did not experience rest in my spirit, [because] I did not find Titus my brother, but saying farewell to them, I departed for Macedonia.

I am not saying [this] as a command, but proving the genuineness of your love by means of the diligence of others.

But I am sending the brothers in order that our boasting about you would not prove to be empty in this case, so that you may be prepared just as I was saying,

What I am saying in this project of boasting, I am not saying as the Lord [would say], but as in foolishness.
