The King James Bible doesn't contain the word "gossip."
It appears once in the New King James, in 1 Timothy 5:13 - And besides they learn to be idle, wandering about from house to house, and not only idle but also gossips and busybodies, saying things which they ought not. (In the King James, the word used in this verse is "tattlers.")
In the NIV, "gossip" is used seven times; the King James instead uses the words, "talebearer," "whisperer," and "whisperings."
