'Web' in the Bible

Then Delilah said to Samson, “You have mocked me all along and told me lies! Tell me how you can be tied up.”He told her, “If you weave the seven braids on my head with the web of a loom—”

She fastened the braids with a pin and called to him, “Samson, the Philistines are here!” He awoke from his sleep and pulled out the pin, with the loom and the web.

His source of confidence is fragile;what he trusts in is a spider’s web.

He leans on his web, but it doesn’t stand firm.He grabs it, but it does not hold up.
