In the sense of "against" which survives only in dialectal English (compare Wright, Dialect Dict., I, 470, for examples) is the King James Version rendering of the dative emauto of 1Co 4:4 (the American Standard Revised Version renders this "against"). In classical Greek the same idiom sunoida with dative = "be conscious" or "be cognizant of" a thing.
