1 Samuel - Chapter 26

Once again David has a chance to kill Saul.  Abishai says

“Today God has delivered your enemy into your hands. Now let me pin him to the ground with one thrust of the spear; I won’t strike him twice.”

But David said to Abishai, “Don’t destroy him! Who can lay a hand on the Lord’s anointed and be guiltless? As surely as the Lord lives,” he said, “the Lord himself will strike him, or his time will come and he will die, or he will go into battle and perish.

Jesus (the Lord's anointed) was pierced by a spear while on the cross:

But when they came to Jesus and found that he was already dead, they did not break his legs. Instead, one of the soldiers pierced Jesus’ side with a spear, bringing a sudden flow of blood and water.

And the man who laid hands on him and betrayed him with a kiss did indeed die:

"With the payment he received for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out."
