The King James Bible addresses gossip in several passages:
Proverbs 16:28 (KJV)
28 A froward man soweth strife: and a whisperer separateth chief friends.
Proverbs 20:19 (KJV)
19 He that goeth about as a talebearer revealeth secrets: therefore meddle not with him that flattereth with his lips.
Proverbs 11:13 (KJV)
13 A talebearer revealeth secrets: but he that is of a faithful spirit concealeth the matter.
Ephesians 4:29 (KJV)
29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
Proverbs 26:20 (KJV)
20 Where no wood is, there the fire goeth out: so where there is no talebearer, the strife ceaseth.
