A fourth function is bringing apparently different cases into a sound relationship. Two passages may use distinct language while conveying connected teachings. The aim is not to erase their differences but to preserve each passage’s context and show any warranted common principle.
One passage may emphasize mercy and another accountability. Their circumstances and audiences matter; both can contribute to a coherent moral instruction without being treated as interchangeable statements.
Caution: not every pair of verses requires an ingenious harmonization. A proposed connection is persuasive only when the wording and context support it.
