HELP 1
Try to make sense of those strange words: is there a way to read them differently than usual?
HELP 2
Try reading the four words from right to left…
HELP 3
Remember that the notice asks you to pronounce numbers…
SOLUTION
Decrypted the coded message (SOUL-SAVE-OUR), you have to rearrange the words to get a complete meaning (SAVE-OUR-SOUL): therefore, the numeric password is 231.
