The most poisonous serpents!
The following is from Spurgeon's sermon,
"Spots in Our Feasts of Charity" #797. Jude 1:12.
Watch constantly against those things
which are thought to be no temptations.
The most poisonous serpents are found
where the sweetest flowers grow.
Cleopatra was poisoned by an asp that was
brought to her in a basket of fair flowers.
Sharp-edged tools, long handled, wound at last.
