The book of proverbs speaks about many thing as well as the topic of cursing and why it is prohibited. There are several verses in the book of proverbs which speaks on the topic of cursing, these verses include:
Proverbs 6: 12, A naughty person, a wicked man, walketh with a froward mouth.” Proverbs 21: 23, “Whoso keepeth his mouth and his tongue keepeth his soul from troubles.” Proverbs 4:24 “Put away from thee a forward mouth, and perverse lips put far from thee.” proverbs 10:32“The mouth of the just bringeth forth wisdom: but the forward tongue shall be cut out.” Proverbs 15: 1 “A soft answer turneth away wrath: but grievous words stir up anger.” Proverbs 30:11 “There is a generation that curseth their father, and doth not bless their mother.” Proverbs 20:20 “Whoso curseth his father or his mother, his lamp shall be put out in obscure darkness.” Proverbs 27: 14 “He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.” Proverbs 30: 9 “Lest I be full, and deny thee, and say, who is the LORD? or lest I be poor, and steal, and take the name of my God in vain.” Proverbs 29:24 “Whoso is partner with a thief hateth his own soul: he heareth cursing, and bewrayeth it not.”
The tongue is said to be a muscular organ in the mouth that is covered with moist, and pink tissue called mucosa. Its vital use is for chewing, swallowing and for speech. (Hoffman). According to Ellen G. White in the book, The Voice in Speech and Song, “It is with the tongue that we offer prayer and praise to God. With the tongue we convince and persuade. With the tongue we comfort and bless, sooth the bruised, wounded soul. With the tongue we may make known the wonders of the grace of God. With the tongue also we may utter perverse things, speaking words that sting like an adder.”
In James 5:3 it is clearly explained that the tongue is a little member that is seen as a fire able to set the body on blaze and thereby corrupt the whole being. Furthermore, in Psalms 109: 17-18 it is clear that a life that is full of misery allows one to curse because of this misery it is made known with their degenerate speech. Thus, God keeps them unhappy by cursing them because of their curse words used in their speech.
Cursing is a well-known theme that can be found in proverbs as well as the reasons why people curse and the consequences that comes after. For example, proverbs 21: 23 which states “Whoso keepeth his mouth and his tongue keepeth his soul from troubles.” This verse simply means if you rule your speech you will save yourself from trouble. Your mouth and tongue are two of your greatest enemies. If you will keep them under control and only speak the right words at the right time, your life will be blessed. Thus, God’s ideal for his children is Godliness and Godlikeness therefore, we must be careful of the words that proceeded from out of our mouth because words can heal, hurt, build or destroy.
