John 19: 23: Then the soldiers, when they had crucified Jesus, took his garments, and made four parts, to every soldier a part; and also his coat: now the coat was without seam, woven from the top throughout.
Jesus’s garment cut into four pieces shows that there were four soldiers guarding the cross.
Four soldiers guarded the cross because there are four beasts that surround the Throne in Heaven (Revelation 4: 6 - 7: And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind. And the first beast was like a lion, and the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle.).
