Abstract

This article tries to demonstrate that the promise made to Nathanael through Gen 38:12-19 in Jn 1:51, foretells the glorification of the Son of Man at the end of his terrestrial journey, described as a descent and an ascent. But this glorification will be carried out by means of the crucifixion ; hence the recourse to two other texts of the O.T. to prove, first in Jn 3:14-15, that the crucifixion of Jesus would be a salvific elevation prefigurated by the serpent raised by Moses on a stake (Nm 21:4-9). But the crucifixion of Jesus is also the ultimate step of the descent of the Son of Man, its salvific value is then proven by the gift of manna, bread descended from heaven (Ex 16:4.15.35 ; Ps 78:24). Jesus, as the true bread of life, transmits the life he continuously receives from his Father to those who remain faithful to him unto the foot of the cross (6:48-58).
