Matthew 27:51-53 New King James Version (NKJV)

51 Then, behold, the veil of the temple was torn in two from top to bottom; and the earth quaked, and
the rocks were split, 52 and the graves were opened; and many bodies of the saints who had fallen asleep
were raised; 53 and coming out of the graves after His resurrection, they went into the holy city and
appeared to many.
