Proverbs 29:5

A man that flattereth his neighbor spreadeth a net for his feet.
– Proverbs 29:5

The word for flattereth means smooth, and indicates smooth talk. Wisdom consistently treats flattery as malicious and ruinous, to be avoided (Proverbs 2:16; 7:5; 26:28; 28:23). Ultimately, the man who gains by flattery will bring ruin upon himself (Proverbs 1:17-19; 26:27; 28:19).
