'Telling' in the Bible

But I am sending these brothers so that our boasting about you may not be empty in this case, so that you may be ready just as I kept telling them.

Now thanks be to God for His indescribable gift [which is precious beyond words]!

for they say, “His letters are weighty and forceful and impressive, but his personal presence is unimpressive and his speech contemptible [of no account].”

For if I want to boast, I will not be a fool, because I will be telling the truth. But I will spare you, so that no one can credit me with something beyond what he sees in me or hears from me,
