1 tn Grk “said to him.”
2 tn Grk “Say that.”
3 tc A majority of witnesses read σου (sou, “your”) here, perhaps for clarification. At the same time, it is possible that the pronoun dropped out through haplography or was excised because of perceived redundancy (there are two other such pronouns in the verse) by א B. Either way, the translation adds it due to the requirements of English style. NA27 includes σου here.
4 tn Grk “His master said to him.”
