- H7225 (רֹאשׁ, rosh): Refers to poison or venom, particularly in the context of serpents.

Usage: In the New Testament, the Greek word "ios" is used metaphorically to describe something that is harmful or corrupting. It can refer to literal poison or venom, as well as the figurative idea of moral or spiritual corruption, akin to rust that eats away at metal.

Cultural and Historical Background: In ancient Greek culture, the concept of "ios" as poison or venom was well understood, as it was a common threat in the natural world, particularly from snakes and other venomous creatures. The metaphorical use of "ios" to describe moral corruption or decay would have resonated with a society familiar with the destructive power of both physical and moral poisons.
