1 Christ preacheth to his disciples to avoid hypocrisy and fearfulness in publishing his doctrine11
11:48 Whom they killed, ye build their sepulchres - Just like them pretending great reverence for the ancient prophets, while ye destroy those whom God sends to yourselves. Ye therefore bear witness by this deep hypocrisy that ye are of the very same spirit with them.
11:49 The wisdom of God, agreeably to this, hath said - In many places of Scripture, though not in these very words, I will send them prophets - Chiefly under the Old Testament: and apostles - Under the New. Mat 23:34.
11:50 The blood of all shall be required of this generation - That is, shall be visibly and terribly punished upon it.
11:51 And so it was within forty years, in a most astonishing manner, by the dreadful destruction of the temple, the city, and the whole nation. Between the temple and the altar - In the court of the temple.
11:52 Ye have taken away the key of knowledge - Ye have obscured and destroyed the knowledge of the Messiah, which is the key of both the present and the future kingdom of heaven; the kingdom of grace and glory. Ye have not entered in - Into the present kingdom of heaven.

12:1 He said to his disciples first - But afterward Luk 12:54 to all the people. Mat 16:6.

4:3 That God would open to us a door of utterance - That is, give us utterance, that we "may open our mouth boldly," Eph 6:19, and give us an opportunity of speaking, so thatnone may be able to hinder.
4:6 Let your speech be always with grace - Seasoned with the grace of God, as flesh is with salt.
