And with many other words did he testify and exhort
For Luke does not give the sermons of the apostles at length, but a compendium, or specimen of them, and some of the more remarkable things in them; and which, it seems, lay partly in testifying concerning Christ, his person, office, grace, righteousness, and salvation; and against sins and errors, and false doctrine; and in "exhorting" to the exercise of grace, and the discharge of duty; or in comforting distressed minds: for the word used signifies to comfort as well as to exhort; though it seems to have the latter sense here, since it follows:
saying, save yourselves from this untoward generation:
meaning, the chief priests, Scribes, and Pharisees, and elders of the people, chiefly, who were a perverse generation of men; and upon whom, for their impenitence and unbelief, for their rejection of the Messiah, and their evil treatment of him, wrath and ruin would come upon them, to the uttermost, very quickly; wherefore the apostle exhorts to separate from them, and not partake of their sins, lest they should also of their plagues; but come out from among them, and so, in a temporal sense, save themselves from the destruction that would quickly come on their nation, city, and temple; and so the Arabic version renders it, "escape from this rough generation".
