Matthew 12:34-36

34 You offspring of vipers! How can you speak good things when you are evil (wicked)? For out of the fullness (the overflow, the [16]superabundance) of the heart the mouth speaks.

35 The good man from his inner good treasure [17]flings forth good things, and the evil man out of his inner evil storehouse [18]flings forth evil things.

36 But I tell you, on the day of judgment men will have to give account for every [19]idle (inoperative, nonworking) word they speak.
