Mark 9:2-9 American Standard Version (ASV)
2 And after six days Jesus taketh with him Peter, and [a]James, and John, and bringeth them up into a high mountain apart by themselves: and he was transfigured before them; 3 and his garments became glistering, exceeding white, so as no fuller on earth can whiten them. 4 And there appeared unto them Elijah with Moses: and they were talking with Jesus. 5 And Peter answereth and saith to Jesus, Rabbi, it is good for us to be here: and let us make three [b]tabernacles; one for thee, and one for Moses, and one for Elijah. 6 For he knew not what to answer; for they became sore afraid. 7 And there came a cloud overshadowing them: and there came a voice out of the cloud, This is my beloved Son: hear ye him. 8 And suddenly looking round about, they saw no one any more, save Jesus only with themselves.
9 And as they were coming down from the mountain, he charged them that they should tell no man what things they had seen, save when the Son of man should have risen again from the dead.
Mark 9:2-9 New International Version (NIV)
2 After six days Jesus took Peter, James and John with him and led them up a high mountain, where they were all alone. There he was transfigured before them. 3 His clothes became dazzling white, whiter than anyone in the world could bleach them. 4 And there appeared before them Elijah and Moses, who were talking with Jesus.
5 Peter said to Jesus, “Rabbi, it is good for us to be here. Let us put up three shelters—one for you, one for Moses and one for Elijah.” 6 (He did not know what to say, they were so frightened.)
7 Then a cloud appeared and covered them, and a voice came from the cloud: “This is my Son, whom I love. Listen to him!”
8 Suddenly, when they looked around, they no longer saw anyone with them except Jesus.
9 As they were coming down the mountain, Jesus gave them orders not to tell anyone what they had seen until the Son of Man had risen from the dead.
