'Telling' in the Bible

But because I am telling the truth, you do not believe me.

Who among you convicts me concerning sin? If I am telling the truth, {why} do you not believe me?

From now [on] I am telling you before [it] happens, in order that when [it] happens you may believe that I am [he].

For some were thinking because Judas had the money box, Jesus was telling him, "Purchase {what we need} for the feast," or that he should give something to the poor.)

His disciples said, "Behold, now you are speaking {plainly} and are telling [us] no figurative saying!

And the one who has seen [it] has testified, and his testimony is true, and that person knows that he is telling the truth, so that you also may believe.
