The Bible describes all kinds of tongues. We are studying tongues that are an unruly evil. Notice the unruly evil of a:
Crafty tongue – Job 15:5 – “thou choosest the tongue of the crafty.” A crafty tongue is cunning and skillful in devising and pursuing a scheme. Absalom used a crafty tongue to steal the hearts of the men of Israel [2 Sam 15:1-6]. The Pharisees and Herodians used a crafty tongue when they tried to catch something in Jesus’ speech that they could use against him to accuse him [Mk 12:13-15]. Tertullus used a crafty tongue when he addressed Felix in Acts 24:1-4. Contrast what these men said with what Nicodemus said in Jn 3:1-2. Nicodemus was sincere.
Deceitful tongue – Ps 52:4 – “thou lovest all devouring words, O thou deceitful tongue.” Ps 120:2, also. This is the wily, subtle tongue just like the devil used against Eve in Gen 3. In Eph 4:14 there are those who lie in wait to deceive young Christians. Jacob had a very deceitful tongue, although he did not want to be known for it [Gen 27:12; 18-24].
Lying tongue – Ps 109:2 – “they have spoken against me with a lying tongue.” This tongue must be put off when we get saved [Eph 4:25]. It is easy to spot; just hold up what it says to the truth. Jezebel and the false witnesses lied against Naboth [1 Ki 21:8-13]. False witnesses lied against Stephen [Acts 6:11-14]. The old prophet lied to the young man of God [1 Ki 13:18]. These are rulers, religious leaders and prophets; and they are liars.
Perverse tongue – Prov 17:20 – “he that hath a perverse tongue falleth into mischief.” A perverse tongue deviates from what is right or good. It is disposed to be contrary. In Acts 20:30 Paul warned of men speaking perverse things, to draw away disciples after them. They take a side that is contrary to the preacher. In 1 Tim 6:5 (see vs. 3-5) they take a side that is contrary to the words of the Lord. Contrast the tongue of wisdom in Prov 8:8, which is never perverse.
Conclusion: be careful when others use these tongues against you. And never use these tongues against others.
