John Trapp on Proverbs 26:9

Verſ. 9. As a thorn goeth up into the hand, &c.] He handleth it hard, as if it were another kind of wood, and it runs into his hand. So do prophane perſons pervert and pollute the holy Scriptures, to their own and other mens deſtruction. By a Parable here the Hebrews underſtand either theſe Parables of Salomon, or the whole Book of God. At this day no people under Heaven doe ſo abuſe Scripture as the Jewes doe. For commending (in their familiar Epiſtles) ſome Letter they have received, they ſay, Eloquia Domini, eloquia pura: The words of my Lord are pure words. When they flatter their friends, Pateat, ſay they, acceſſus ad aditum ſanctitatis tuae. Weemſe. Let me have acceſſe to the ſanctuary of thy holineſſe. When they would teſtifie themſelves thankful, Nomini tuo pſallam, I will ſing praiſe to thy Name. When they complain, friends forſake them, Lord, ſay they, thou goeſt not forth with our armies. When they invite their friends to a Banquet or a Wedding, In thee have I truſted, let me not be put to confuſion. Loe thus doe theſe witleſſe wicked wretches abuſe Gods Parables, and take his Name in vain. Whereas the very Heathen could ſay, Non loquendum de Deo ſine lumine, God is not to be talked of lightly, looſely, diſreſpectively. Thou ſhalt fear that glorious and fearful Name, Jehovah thy God, ſaith Moſes their own Law-giver, Deut. 28.58.
