² tc The majority of mss (א L W 058 0281 Ë^1,13 33 Ï it sy^p,h co) begin the slave’s plea with “Lord” (κύριε, kurie), though a few important witnesses lack this vocative (B D Θ 700 pc lat sy^s,c Or Chr). Understanding the parable to refer to the Lord, scribes would be naturally prone to add the vocative here, especially as the slave’s plea is a plea for mercy. Thus, the shorter reading is more likely to be authentic.
