7 But “perceive;” scrutinizing diligently; and if any kind of gain falls in your way, look not only at the gain, but inspect it carefully, lest somewhere death and sin lurk within the gain; and should you perceive this, fly from it. Again, when some delight or pleasure may chance to present itself, look not only at the pleasure; but lest somewhere in the depth of the pleasure some iniquity should lie enveloped, search closely, and if you discover it, hasten away! And should any one counsel, or flatter, or cajole, or promise honours, or any other such thing whatever, let us make the closest investigation; and look at the matter on all sides, lest something pernicious, something perilous, should perchance befall us through this advice, or honour, or attention, and we run upon it hastily and unwittingly.
For if there were only one or two snares, the precaution would be easy. But now, hear how Solomon speaks when he wishes to set forth the multitude of these; “Perceive that you go in the midst of snares;” he does not say, that you “go by” snares, but “in the midst” of snares. On either side are the pit-falls; on either side the deceits. One goes into the forum; one sees an enemy; one is inflamed by the bare sight of him! One sees a friend honoured; one is envious! One sees a poor man; one despises and takes no notice of him!
One sees a rich man; one envies him! One sees some one injuriously treated; one recoils in disgust! One sees some one acting injuriously; one is indignant! One sees a handsome woman, and is caught! Do you see, beloved, how many snares there are? Therefore it is said, “Remember that you go in the midst of snares.” There are snares in the house, snares at the table, and snares in social intercourse. Very often a person unwittingly, in the confidence of friendship, gives utterance to some particular of those matters which ought not to be repeated again, and so great a peril is brought about, that the whole family is thereby ruined!
