Mark 11:23

23
I assure you: This is a phrase used only by Jesus to testify to the certainty and importance of His words; in Mt, Mk and Lk it is literally Amen, I say to you, and in Jn it is literally Amen, amen, I say to you.
I assure you: b If anyone says to this mountain, ‘Be lifted up and thrown into the sea,’ and does not doubt c in his heart, but believes d that what he says will happen, it will be done for him. e
