They.

Psalm 22:16, 17
For dogs surround me; a band of evil men encircles me; they have pierced my hands and feet. . . .

Zechariah 12:10
Then I will pour out on the house of David and on the residents of Jerusalem a spirit of grace and prayer, and they will look on Me, the One they have pierced. They will mourn for Him as one mourns an only child, and weep bitterly for Him as one grieves a firstborn son.

Revelation 1:7
Behold, He is coming with the clouds, and every eye will see Him--even those who pierced Him. And all the tribes of the earth will mourn because of Him. So shall it be! Amen.
