13:3 Foolish prophets - Foolish prophets are not of God's sending: for whom he sends, he either finds fit, or makes fit. Where he gives warrant, he gives wisdom. Their own spirit - Not the spirit of God. Seen nothing - God hath shewed them no vision.
13:1-9 Where God gives a warrant to do any thing, he gives wisdom. What they delivered was not what they had seen or heard, as that is which the ministers of Christ deliver. They were not praying prophets, had no intercourse with Heaven; they contrived how to please people, not how to do them good; they stood not against sin. They flattered people into vain hopes. Such widen the breach, by causing men to think themselves deserving of eternal life, when the wrath of God abides upon them.
