Proverbs 26:21-28

²¹Like breath on coals and wood on fire, so a man given to argument gets a fight started.

²²The words of one who says evil of his neighbour secretly are like sweet food, they go down into the inner parts of the stomach.

²³Smooth lips and an evil heart are like a vessel of earth plated with silver waste.

²⁴With his lips the hater makes things seem what they are not, but deceit is stored up inside him;

²⁵When he says fair words, have no belief in him; for in his heart are seven evils:

²⁶Though his hate is covered with deceit, his sin will be seen openly before the meeting of the people.

²⁷He who makes a hole in the earth will himself go falling into it: and on him by whom a stone is rolled the stone will come back again.

²⁸A false tongue has hate for those who have clean hearts, and a smooth mouth is a cause of falling.
