John 19:18 – There they crucified Him, and with Him two others, one on either side, and Jesus between them.
​Jesus had two metal nails in His hands when He was being crushed by death.
​Revelation 1:18 – I died, and behold I am alive forevermore, and I have the keys of death and hades.
​After dealing with the issue of sin, Jesus has two metal keys in His hands; one for death and one for hades.
