Matthew 17:9-13 New American Bible (Revised Edition) (NABRE)
9 As they were coming down from the mountain, Jesus charged them, “Do not tell the vision[a] to anyone until the Son of Man has been raised from the dead.” 10 [b]Then the disciples asked him, “Why do the scribes say that Elijah must come first?” 11 He said in reply,[c] “Elijah will indeed come and restore all things; 12 but I tell you that Elijah has already come, and they did not recognize him but did to him whatever they pleased. So also will the Son of Man suffer at their hands.” 13 [d]Then the disciples understood that he was speaking to them of John the Baptist.
