The word that I said unto you, 1 Thessalonians 13:16, to press you to humility, and a mutual serving of one another in love; and which I spake to you, Matthew 10:24, when I first sent you out; and I spake it then to you upon the very same account that I now speak it. You that are my servants cannot look to fare better with the world than I that am your Master; you know they have hated me, you must expect they should persecute you: if there be any of them whose hearts God shall incline to keep my sayings, they will also keep your words, which are but my sayings explained to them, and further pressed upon them.

20 Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also.
