Luke 9:18, 28

Now it happened that as Jesus was praying privately, the disciples were with Him, and He asked them, “Who do the crowds say that I am?” [Matt 16:13-16; Mark 8:27-29]

Now about eight days after these teachings, He took along Peter and John and James and went up on the mountain to pray. [Matt 17:1-8; Mark 9:2-8]
