'Mountain' in the Bible

He went up into the mountain, and called to himself those whom he wanted, and they went to him.

After he had taken leave of them, he went up the mountain to pray.

After six days Jesus took with him Peter, James, and John, and brought them up onto a high mountain privately by themselves, and he was changed into another form in front of them.

As they were coming down from the mountain, he commanded them that they should tell no one what things they had seen, until after the Son of Man had risen from the dead.

For most certainly I tell you, whoever may tell this mountain, 'Be taken up and cast into the sea,' and doesn't doubt in his heart, but believes that what he says is happening; he shall have whatever he says.
