Specification excludes some instances from general wording by relevant evidence; qualification adds a restriction to an otherwise unrestricted expression. Neither process necessarily means that an earlier ruling ceased to operate at a later time.
Technical abrogation depends on sequence: an operative ruling is lifted by later revealed evidence. If two texts can be reconciled through recognized principles, apparent tension alone does not establish abrogation.
Illustration: excluding a specified subgroup from a general command is not equivalent to ending the whole earlier command. This helps explain why counts of abrogated verses vary.
