1 He reproveth them, because in holy assemblies10
10:31 Therefore - To close the present point with a general rule, applicable not only in this, but in all cases, Whatsoever ye do - In all things whatsoever, whether of a religious or civil nature, in all the common, as well as sacred, actions of life, keep the glory of God in view, and steadily pursue in all this one end of your being, the planting or advancing the vital knowledge and love of God, first in your own soul, then in all mankind.
10:32 Give no offence - If, and as far as, it is possible.
10:33 Even as I, as much as lieth in me, please all men.

Mark, Chapter 1, verses 40-45
32 many diseased persons, 41 and cleanseth the leper1
1:44 See thou say nothing to any man - But our blessed Lord gives no such charge to us. If he has made us clean from our leprosy of sin, we are not commanded to conceal it. On the contrary, it is our duty to publish it abroad, both for the honour of our Benefactor, and that others who are sick of sin may be encouraged to ask and hope for the same benefit. But go, show thyself to the priest, and offer for thy cleansing what Moses commanded for a testimony to them - The priests seeing him, pronouncing him clean, Lev 13:17, Lev 13:23, Lev 13:28, Lev 13:37, and accordingly allowing him to offer as Moses commanded, Lev 14:2, Lev 14:7, was such a proof against them, that they durst never say the leper was not cleansed; which out of envy or malice against our Saviour they might have been ready to say, upon his presenting himself to be viewed, according to the law, if by the cleansed person's talking much about his cure, the account of it had reached their ears before he came in person. This is one great reason why our Lord commanded this man to say nothing.
1:45 So that Jesus could no more openly enter into the city - It was also to prevent this inconvenience that our Lord had enjoined him silence.
