Luke 22:7  KJV  "Then came the day of unleavened bread, when the passover must be killed."

Interpretation based on the following study:  To be set to accomplish, moreover, the Son in the right time completed God's assigned Purpose to Deliver and Save, Fulfilling and Finishing, Bringing to an End, to Preserve in Completeness.  He accomplished in devotion, consecrated and set apart uncorrupted, resting and giving Himself wholly and openly to fulfill and join us, confirming and fastening us to belong to God in His Presence permanently.  He became our substitute to represent us, paying the full price for our redemption to save and deliver us to return to God in His Will and Way.
