The Bible also uses spiders to teach spiritual lessons....
On the thread she spins, or on the flies and bees she catches in her web. This is a small creature, yet very wise; what a curious thread does she spin! what a fine web does she weave! with what exactness and proportion is it framed! as if she understood the rules of mathematics and architecture;
and is in kings' palaces; as well as in the houses of poor people, and in temples also; we read of one in the temple of Ceres, which drew its web over the face of the image: and though her webs are oftentimes destroyed, especially in kings' palaces; yet such is her constancy and assiduity, and her unwearied application to business, that, as fast as they are destroyed, she attempts to restore them.
This creature is an emblem of diligence in things temporal and spiritual; which those that use in the former sense shall stand before kings, and not before mean men; and in the latter sense shall have the presence of the King of kings, and dwell in his palace here and hereafter: also of worldly minded men, who labour to be rich; spend their time, and take a great deal of pains for mere trifles; weave curious webs, and, after all, only catch flies; and those they cannot hold, uncertain riches, which make themselves wings and fly away.
Likewise this creature may resemble hypocrites, whose hope and trust are as the spider's web, built upon their own righteousness, spun out of their own hearts; a fine, thin, slender thread, which cannot bear one stroke of the besom of divine justice; such as these are in the palaces of Christ the King, are in his churches, hypocrites in Zion; see Job 8:13.
