A man who lacks sense strikes hands in pledge and puts up security before his neighbor.
In context
16What good is money in the hand of a fool to buy wisdom, when he has no sense? 17A friend loves at all times, and a brother is born for adversity. 18A man who lacks sense strikes hands in pledge and puts up security before his neighbor. 19Whoever loves an offense loves strife; whoever builds his gate high is asking for ruin. 20The crooked in heart finds no good, and the twisted of tongue falls into evil.
