Proverbs 1:17

Surely in vain the net is spread in the sight of any bird - This is a proverb of which the wise man here makes a particular use; and the meaning does not seem as difficult as some imagine. The wicked are represented as lurking privily for the innocent. It is in this way alone that they can hope to destroy them and take their substance; for if their designs were known, proper precautions would be taken against them; for it would be vain to spread the net in the sight of those birds which men wish to ensnare. Attend therefore to my counsels, and they shall never be able to ensnare thee.
