Then Jesus, being filled with the Holy Spirit, returned from the Jordan and was led by the Spirit into the wilderness, being tempted for forty days by the devil. And in those days He ate nothing, and afterward, when they had ended, He was hungry. (Luke 4:1–2; NKJV)

After Jesus’ baptism by John in the Jordan, the Holy Spirit led Jesus into the wilderness, where He endured temptation for 40 days.
