This is clearest in verses 26 and 27: "26 And after crying out and convulsing him terribly, it [the unclean spirit] came out, and the boy was like a corpse, so that most of them [the people in the crowd] said, 'He is dead.' 27 But Jesus took him by the hand and lifted him up, and he arose." After a deathlike state, the boy arises. The verb here is ἀνίστημι, and this is the same verb that's used to refer to the resurrection of the dead in John 11 (where Jesus raises Lazarus from the dead).
