ἅπτω
háptō · verb · “to kindle, set on fire”
Haptō means to touch, kindle, or set on fire. Jesus' touch heals the leper; God's truth sets the heart on fire — both senses run through the New Testament.
Haptō covers a wide field — touching, lighting a lamp, even sexual contact. In the Gospels its loudest use is Jesus reaching out to touch what others would not: lepers, the dead, the unclean.
His touch did not defile him; it healed them. The chapter of Mark 1 alone shows him touching the untouchable. The same verb names the kindling of fire — and disciples whose hearts «burn» as he opens the Scriptures (Luke 24:32).
Definition: properly, to fasten to, i.e. (specially) to set on fire
KJV usage: kindle, light
