Jesus, full of the Holy Spirit, returned from the Jordan, and was led by the Spirit into the wilderness
The wilderness ... mentioned here cannot be exactly located.  It could have been anywhere on the western side of the Jordan river.  "Tradition locates the place as Quarantania, a mountain just west of Jericho."[4] Wherever it was, it was a howling wilderness, alive with wild beasts (Mark 1:12f), and contrasting vividly with the garden of Eden where the first Adam succumbed to the wiles of Satan.  Satan seemed to have that encounter in mind, as indicated by his approach to the second Adam with regard to eating, the same strategy that had succeeded in Eden, and reinforced here by circumstances much more favorable to the evil one.
