not disobey = “not” + “pay no attention to”

[vil]

Dear teachers,

Would you be kind enough to tell me whether there is something wrong with the following sentences which I found in different English written works?

Then Sun Tzu sent a messenger to the King saying: "Your soldiers, Sire, are now properly drilled and disciplined, and ready for your majesty's inspection. They can be put to any use that their sovereign may desire; bid them go through fire and water, and they will not disobey."

Moses said, "Allah willing, you will find me patient and I will not disobey you in aught.”

If you choose not to show these manners you do not disobey but simply ignore it.

I entertain suspicion that in the sentences in question are used two forms of negation in the same clause.

For example : not disobey = “not” + “pay no attention to” that reads very, very oddly.

Regards,

V.

I honestly don't understand the problem with 'will not disobey', it seems quite a normal construction to me, and it says quite clearly what it means.
