Sirach 23:21

21 This man shall be punished in the streets of the city, and where he suspecteth not he shall be taken.

Sirach 23:21 In-Context

19 Such a man only feareth the eyes of men, and knoweth not that the eyes of the Lord are ten thousand times brighter than the sun, beholding all the ways of men, and considering the most secret parts.
20 He knew all things ere ever they were created; so also after they were perfected he looked upon them all.
21 This man shall be punished in the streets of the city, and where he suspecteth not he shall be taken.
22 Thus shall it go also with the wife that leaveth her husband, and bringeth in an heir by another.
23 For first, she hath disobeyed the law of the most High; and secondly, she hath trespassed against her own husband; and thirdly, she hath played the whore in adultery, and brought children by another man.
