I admit that Murray's "indestructible" makes more sense to me than Taylor's "incorruptible" - though "incorruptible" did lead me along a thought-train that chugged close to (probably popular-level) stoic-ish thought whereby our obviously mixed-bag world might look to be corrupted (by death, decay, disease, ignorance, and what have you) but since such things are part of the world that is itself of divine provenance, these things too are not Uppercase Corruption of divine perfection and just reveal our own prejudices and obscured understandings of "Gods' will."

So, originally I wondered if this was a hint of something hidden... but as Murray's translation doesn't have that same implication, I'm guessing I was just off on a tangent.
