foul (raphas; akdthartos): The verb "to foul" (defile) occurs as the translation of raphas, "to trample" or "muddle" (streams) (Eze 32:2; 34:18); of chalmar, "to burn," "to be red" (Job 16:16, "My face is foul with weeping," the American Standard Revised Version and the English Revised Version, margin "red"); of mirpas, "a treading" (Eze 34:19). The adjective is the translation of akathartos, "unclean," "impure," "wicked" (Mr 9:25; Re 18:2, "foul spirit," the Revised Version (British and American) "unclean"), and of cheimon, "winter," "stormy or foul weather" (Mt 16:3). the Revised Version (British and American) has "The rivers shall become foul" (Isa 19:6) instead of the King James Version "They shall turn the rivers far away," the English Revised Version "The rivers shall stink."

Vine's Expository Dictionary of New Testament Words
1 Strong's Number: g169 Greek: akathartos


denotes "unclean, impure" (a, negative, and kathairo, "to purify"),

(a) ceremonially, e.g., Act 10:14, 28;

(b) morally, always, in the Gospels, of unclean spirits; it is translated "foul" in the AV of Mar 9:25; Rev 18:2, but always "unclean" in the RV. Since the word primarily had a ceremonial significance, the moral significance is less prominent as applied to a spirit, than when poneros, "wicked," is so applied. Cp. akatharsia, "uncleanness."

Note: In Rev 17:4 the best mss. have this word in the plural, RV, "the unclean things" (akathartes, "filthiness," in some mss.).
