Mark 11:1, 22-23

As Jesus and his disciples approached Jerusalem, they came to the towns of Bethphage and Bethany on the Mount of Olives. Jesus sent two of them on ahead.

Then Jesus said to the disciples, “Have faith in God. I tell you the truth, you can say to this mountain, ‘May you be lifted up and thrown into the sea,’ and it will happen. But you must really believe it will happen and have no doubt in your heart.
