Matthew 17:8-10

Young's Literal Translation

⁸ and having lifted up their eyes, they saw no one, except Jesus only.

⁹ And as they are coming down from the mount, Jesus charged them, saying, `Say to no one the vision, till the Son of Man out of the dead may rise.'

¹⁰ And his disciples questioned him, saying, `Why then do the scribes say that Elijah it behoveth to come first?'
