Sirach 28:24Ben Sira, Ecclesiasticus
22 It has no power over the godly; they will not be burned in its flame. 23 Those who forsake the Lord will fall into its power; it will burn among them and will not be put out. It will be sent out against them like a lion; like a leopard it will mangle them. 24 As you fence in your property with thorns, 25 so make a door and a bolt for your mouth. As you lock up your silver and gold, so make balances and scales for your words. 26 Take care not to err with your tongue, and fall victim to one lying in wait.
Ambrose On the Christian Faith 1.6
This monster's cavern, your sacred Majesty, thick laid, as seafaring men do say it is, with hidden lairs, and all the neighbourhood thereof, where the rocks of unbelief echo to the howling of her black dogs, we must pass by with ears in a manner stopped. For it is written: Hedge your ears about with thorns; and again: Beware of dogs, beware of evil workers; and yet again: A man that is an heretic, avoid after the first reproof, knowing that such an one is fallen, and is in sin, being condemned of his own judgment. So then, like prudent pilots, let us set the sails of our faith for the course wherein we may pass by most safely, and again follow the coasts of the Scriptures.
