"False prophets" and "false teachers" warnings from the Bible!

Are there any biblical warnings against false prophets and false teachers?
“And the brethren immediately sent away Paul and Silas by night unto Berea: who coming [thither] went into the synagogue of the Jews. These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so. Therefore many of them believed; also of honourable women which were Greeks, and of men, not a few.” (Acts 17:10 to 12)
