Mark 9:4 YLT

²  And after six days doth Jesus take Peter, and James, and John, and bringeth them up to a high mount by themselves, alone, and he was transfigured before them,

³  and his garments became glittering, white exceedingly, as snow, so as a fuller upon the earth is not able to whiten 'them'.

⁴  And there appeared to them Elijah with Moses, and they were talking with Jesus.

⁵  And Peter answering saith to Jesus, 'Rabbi, it is good to us to be here; and we may make three booths, for thee one, and for Moses one, and for Elijah one:'

⁶  for he was not knowing what he might say, for they were greatly afraid.
