Leprosy - Vine's Expository Dictionary of New Testament Words
Leprosy[ 1,,G3014, lepra ]
akin to lepros (above), is mentioned in Matthew 8:3; Mark 1:42; Luke 5:12-Luke 5:13. In the removal of other maladies the verb to heal" (iaomai) is used, but in the removal of "leprosy," the verb "to cleanse" (katharizo), save in the statement concerning the Samaritan, Luke 17:15, "when he saw that he was healed." Matthew 10:8; Luke 4:27 indicate that the disease was common in the nation. Only twelve cases are recorded in the NT, but these are especially selected. For the Lord's commands to the leper mentioned in Matthew 8 and to the ten in Luke 17, See Lev. 14:2-32.
