The largest ever found had a leg-span of more than 28cm

Here are three possibilities:
So are the paths of all that forget God; and the hypocrite’s hope shall perish:
Whose hope shall be cut off, and whose trust shall be a spider’s web.
He shall lean upon his house, but it shall not stand: he shall hold it fast, but it shall not endure.
There be four things which are little upon the earth, but they are exceeding wise:
The ants are a people not strong, yet they prepare their meat in the summer; The conies are but a feeble folk, yet make they their houses in the rocks; The locusts have no king, yet go they forth all of them by bands;
The spider taketh hold with her hands, and is in kings’ palaces.
Behold, the LORD’S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear:
But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear. For your hands are defiled with blood, and your fingers with iniquity; your lips have spoken lies, your tongue hath muttered perverseness. None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity. They hatch cockatrice’ eggs, and weave the spider’s web: he that eateth of their eggs dieth, and that which is crushed breaketh out into a viper.
Their webs shall not become garments, neither shall they cover themselves with their works: their works are works of iniquity, and the act of violence is in their hands.

Due to excessive habitat destruction, man is the spider's worst enemy.
Round worms and mites are parasites that attach themselves to the spiders, sucking them dry of their vital fluids.

Almost every small carnivore is the spider's enemy.

- Emphasize that even though there are some poisonous spiders, except for a few rare cases, they bite humans only in self-defense. The human race needs spiders in order to survive.
11a
Spiders are predators and so they eat flies and other small annoying insects. Many of these insects destroy our crops and gardens. Other insects caught in their webs can cause disease in humans.
Dust mites live in our homes and eat the dead skin that comes off our bodies. Many people are allergic to dust mites. Spiders eat the Dust Mites, thereby assisting in allergen control.
Spiders are an integral part of the food chain. Because the spider eats and is eaten, it helps to keep the ecosystem balanced. Without spiders the ecosystem would become imbalanced, seriously damaging many living things, including humans.
11b
Some spiders are venomous. Their bites can range from painful to deadly if the correct treatment is not used within a short time after the bite.
Most people are afraid of spiders, so if a property has either too many spiders or poisonous spiders, it would be hard to sell that property.
Spiders make webs in unwelcome places, like corners of rooms or between limbs of trees over a path. These webs cause us to spend time and money removing them. Their webs also trap dust that can cause an allergic reaction in some people.
