He would be killed (crucified) and rise from the dead

From that time Jesus began to show His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised up on the third day.

(Matthew 16:21)

Mat 20:18 "Behold, we are going up to Jerusalem; and the Son of Man will be delivered to the chief priests and scribes, and they will condemn Him to death,

Mat 20:19 and will hand Him over to the Gentiles to mock and scourge and crucify Him, and on the third day He will be raised up."

And He began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes, and be killed, and after three days rise again.

(Mark 8:31)

"The Son of Man must suffer many things and be rejected by the elders and chief priests and scribes, and be killed and be raised up on the third day."

(Luke 9:22)

Mat 17:9 As they were coming down from the mountain, Jesus commanded them, saying, "Tell the vision to no one until the Son of Man has risen from the dead."

And while they were gathering together in Galilee, Jesus said to them, "The Son of Man is going to be delivered into the hands of men; and they will kill Him, and He will be raised on the third day." And they were deeply grieved.

(Matthew 17:22-23)

"For this reason the Father loves Me, because I lay down My life so that I may take it again. "No one has taken it away from Me, but I lay it down on My own initiative. I have authority to lay it down, and I have authority to take it up again. This commandment I received from My Father."

(John 10:17-18)
