'Added' in the Bible

"I tell you all in most solemn truth," He added, "that you shall see Heaven opened wide, and God's angels going up, and coming down to the Son of Man."

So Jesus added, "Because of this I told you that no one can come to me unless the Father has allowed him to come."

So Jesus said, “When you lift up the Son of Man [on the cross], you will know then [without any doubt] that I am He, and that I do nothing on My own authority, but I say these things just as My Father taught Me.

After he said this, he added, "Our friend Lazarus has fallen asleep. But I am going there to awaken him."
