He was nailed to a tree with more than one nail, and I am not quite sure why you are thinking it might only be one nail. One nail in each hand/arm/wrist whatever, and one in both feet. There was also possibly rope there also to hold him up. The Bible was not nececsarily meant to be a precise history.

the romans had many different ways to crucify a person. there was a crucifix in the shape of an X, a capital T, a lower case t, and sometimes they just nailed someone to a pole. the capital T, i believe, was the most common form because it was a somewhat permanent structure and easy to put people on. while many people believe Jesus was crucified on a cross in the shape of a lower case t, it's more likely that it was a T-shape. either shape would have His arms spread out, requiring 2 nails. . according to the Bible, Jesus had to carry the crossbeam along a path to His execution site, which presumably verifies that He was hung on a t or T-shaped cross, not on a pole or tree.

John did not write his gospel in English, using the word "Nails". he wrote it in Greek. in Greek, for the word Nails is uesd "Helos" and it means "a nail". it is your English bible whhere uesd the word Nails. Maybe you should read the bible first in Greek. However, the Greek manuscriptures are not 100% correct...

John did not write his gospel in English. He did not used the word nails. John wrote it in Greek and used the word helos. helos means Nail.

The Cyclopaedia of Biblical, Theological, and Ecclesiastical Literature, by M’Clintock and Strong, comments: ‘Much time and trouble have been wasted in disputing as to whether three or four nails were used in fastening the Lord. Nonnus affirms that three only were used, in which he is followed by Gregory Nazianzen. The more general belief gives four nails, an opinion which is supported at much length and by curious arguments by Curtius. Others have carried the number of nails as high as fourteen.’—Volume II, page 580. Matthew 27:35 merely says: “When they had impaled him they distributed his outer garments by casting lots.” Little detail is given, as in Mark, Luke and John. After Jesus’ resurrection, Thomas said: “Unless I see in his hands the print of the nails and stick my finger into the print of the nails and stick my hand into his side, I will certainly not believe.” (John 20:25) So even though criminals sometimes were bound to a stake with ropes, Jesus was nailed. Some have also concluded from John 20:25 that two nails were used, one through each hand. But does Thomas’ use of the plural (nails) have to be understood as a precise description indicating that each of Jesus’ hands was pierced by a separate nail? In Luke 24:39 the resurrected Jesus said: “See my hands and my feet, that it is I myself.” This suggests that Christ’s feet also were nailed. Since Thomas made no mention of nailprints in Jesus’ feet, his use of the plural “nails” could have been a general reference to multiple nails used in impaling Jesus. Thus, it just is not possible at this point to state with certainty how many nails were used. Any drawings of Jesus on the stake should be understood as artists’ productions that offer merely a representation based on the limited facts that we have. Debate over such an insignificant detail should not be permitted to becloud the all-important truth that “we became reconciled to God through the death of his Son.”—Romans 5:10.

Perhaps because he had two handS.
