examines quotations where the New Testament author quotes the Septuagint but changes the tense-form of the verb, substituting one aspectual value for another, often in furtherance of a typological, prophetic, or theological connection. Taking into account various models of the verb in Koine Greek, including tenseless and aspect-prominent proposals, this study employs contrastive substitution to analyze the significance of aspectual substitution in quotations, concluding that the future tense-form encodes perfective aspect and is marked for future temporal reference.
