Acts 18:10

For I am with thee
According to his promise, ( Matthew 28:20 ) not only to assist in the ministry of the word, to give light into it, and liberty to preach it, and success in it, but to keep and preserve him from being hurt by men:

and no man shall set on thee;
attack thee, or lay hands on thee:

to hurt thee;
to do any injury to thy person, to thy body, in any part of it: wicked men cannot strike a blow, or do the least damage to a servant of Christ without his permission; he can tie their hands, and restrain their rage.

For I have much people in this city;
this wicked and luxurious city; there were many here who were yet in their sins, in a state of unregeneracy, whom God had chosen to be his people, and had taken into his covenant as such; were given to Christ as his peculiar people, and whom he had redeemed with his precious blood: they were his people both by gift and purchase, before they were called by grace; and because of this his interest in them, he will have his Gospel continued for the gathering them in to himself; for Christ will lose none of his, all shall come unto him: from all which it appears, that Christ has a people who are related to him, and he has an interest in, before they are effectually called by grace; for this refers not to the many Corinthians who had heard and believed, and were baptized, but to some that had not, and were yet to be called; not the Jews in this city, Christ's own nation, nor all the inhabitants of it who were in some sense Christ's people, being made and supported in their beings by him, are intended; but a special people among the Gentiles, the same with the other sheep Christ speaks of, ( John 10:16 ) not yet of his fold; a people beloved of God, chosen in Christ, given to him, and with whom a covenant was made in him, for whom Christ undertook, in whose name he acted, and for whom he received blessings and promises, as well as took the care and charge of their persons; for the sake of these he assumed human nature, and suffered and died; towards these his heart always is; his eye is upon them, and he knows them, and where they are; and therefore he will look them up and find them out, and they shall be brought to believe in him, and shall not perish, but have everlasting life: and it may be further observed, that Christ has "many" such, though they are but comparatively few, yet in themselves they are a great number; yea, he has sometimes many of these in the worst of places, and among the vilest of men; and for the sake of these, in order to select and separate them from the rest, is the Gospel preached and continued. The ministers of it are sent here and there, where such persons are, and there they are continued till they are gathered in; yea, on this account both the Gospel and its preachers are continued in the world; and even the world itself, for the sake of these, till they are brought in, and then it will be destroyed; and it may be also remarked, that for the encouragement of Gospel ministers, Christ promises his presence and protection, and which was fulfilled in the Apostle Paul at Corinth; who though he stayed there a year and six months, none were suffered to do him any injury; and when an insurrection was made within that time, yet the apostle escaped, and quietly departed elsewhere.
