Spider: The trust of the hypocrite is compared to the spider's web or house (Job 8:14). It is said of the wicked by Isaiah that they "weave the spider's web" (Job 59:5), i.e., their works and designs are, like the spider's web, vain and useless. The Hebrew word here used is 'akkabish, "a swift weaver."
In Proverbs 30:28 a different Hebrew word (semamith) is used. It is rendered in the Vulgate by stellio, and in the Revised Version by "lizard." It may, however, represent the spider, of which there are, it is said, about seven hundred species in Palestine.
