SEV Biblia, Chapter 5:8
Porque le decía: Sal de este hombre, espíritu inmundo.
John Gill's Bible Commentary
Ver. 8. For he said unto him , etc..] Or he had said unto him, as soon as he came up to him, and fell before him; even before he had confessed, and adjured him; and which indeed drew out the confession from him, that he was superior to him, and therefore became his supplicant: come out of the man, thou unclean spirit ; which was said with so much authority and power, that there was no withstanding it: the devil knew he was not a match for him; that he must, at his command, quit his possession, and therefore fell to confession and entreaty. Christ will not dwell where Satan does; when therefore he is about to take up his residence in the hearts of any, he outs with Satan; he binds the strong man armed, and dispossesses him; he causes the spirit of uncleanness to depart; he sanctifies the heart by his grace and Spirit, and so makes it a proper habitation for him to dwell in by faith; and this is done by mighty power: a man cannot deliver himself out of the hands of Satan, or cause him to quit his hold of him, or the unclean spirit to depart; nor can he sanctify and cleanse himself, and make himself meet for the master's use: this is all owing to efficacious grace.
Matthew Henry Commentary
Verses 1-20 - Some openly wilful sinners are like this madman. The commands of the law are as chains and fetters, to restrain sinners from their wicke courses; but they break those bands in sunder; and it is an evidence of the power of the devil in them. A legion of soldiers consisted of sin thousand men, or more. What multitudes of fallen spirits there must be and all enemies to God and man, when here was a legion in one poor wretched creature! Many there are that rise up against us. We are not match for our spiritual enemies, in our own strength; but in the Lord and in the power of his might, we shall be able to stand against them though there are legions of them. When the vilest transgressor i delivered by the power of Jesus from the bondage of Satan, he wil gladly sit at the feet of his Deliverer, and hear his word, wh delivers the wretched slaves of Satan, and numbers them among his saints and servants. When the people found that their swine were lost they had a dislike to Christ. Long-suffering and mercy may be seen even in the corrections by which men lose their property while their lives are saved, and warning given them to seek the salvation of their souls. The man joyfully proclaimed what great things Jesus had done for him. All men marvelled, but few followed him. Many who cannot but wonder at the works of Christ, yet do not, as they ought, wonder afte him.

Vincent's NT Word Studies
8. For he said (elegen). Imperfect tense, he was saying; the force of which is lost both in the A.V. and Rev. The imperfect gives the reason for this strange entreaty of the demon. Jesus was commanding, was saying " come out; " and, as in the case of the epileptic child at the Transfiguration Mount, the baffled spirit wreaked his malice on the man. The literal rendering of the imperfect brings out the simultaneousness of Christ's exorcism, the outbreak of demoniac malice, and the cry Torment me not.
Robertson's NT Word Studies
5:8 {For he said} (elegen gar). For he had been saying (progressive imperfect). Jesus had already repeatedly ordered the demon to come out of the man whereat the demon made his outcry to Jesus and protested. #Mt 8:29 had "before the time" (pro kairou) and #8:31 shows that the demons did not want to go back to the abyss (ten abusson) right now. That was their real home, but they did not wish to return to the place of torment just now.
