1 JAS 4:4 It would be possible to classify μοιχαλίς in JAS 4:4 as being a substantive and thus having a meaning different from μοιχαλίς in MAT 12:39, where it occurs as an adjective. However, the regular use of adjectives in the role of substantives does not warrant setting up separate meanings, especially since the adjectival form may be regarded as being attributive to a syntactically implied substantive.
