40 Grk “falling therefore the slave bowed down to the ground.” The redundancy of this expression signals the desperation of the slave in begging for mercy.
41 The majority of (א L W 058 0281 f1, 13 33 𝔐 it syp,h co) begin the slave’s plea with “Lord” (κύριε, kurie), though a few important witnesses lack this vocative (B D Θ 700 lat sys,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.
