¹ tc There are several variants at this point in the text, most of them involving the addition of προσλαβοῦ (proslabou, “receive, accept”) at various locations in the verse. But all such variants seem to be motivated by the harsh syntax of the verse without this verb. Without the verb, the meaning is that Onesimus is Paul’s “very heart,” though this is an awkward expression especially because of τουτ᾿ ἔστιν (tout’ estin, “this is, who is”) in the middle cluttering the construction. Nowhere else in the NT is σπλάγχνα (splanchna, here translated “heart”) used in apposition to people. It is thus natural that scribes would want to fill out the text, and they did so apparently with a verb that was ready at hand (borrowed from v. 17). With the verb the sentence is converted into an object-complement construction: “I have sent him back to you; accept him, that is, as my very heart.” But both the fact that some significant witnesses (א* A F G 33 [69 2400 SBL]) lack the verb, and that its location floats in the various constructions that have it, suggest that the initial text did not have προσλαβοῦ.

² tc The phrase “whom he named apostles” is lacking in the majority of mss (A C² D L ƒ¹ 33 565 579 1241 1424 M latt sy; SBL). Several primary Alexandrian and other key witnesses (א B C* W Δ Θ ƒ¹³ 28 co) include the phrase, rendering the external evidence strongly in favor of this reading. It is possible that the Alexandrian witnesses have inserted these words to bring the text in line with Luke 6:13 (TCGNT 69), but against this is the internal evidence of Mark’s style: Mark tends toward gratuitous redundancy. However, significant Western and Byzantine mss along with other authorities lack the clause, which is against the Byzantine tendencies. The key issue, however, is that both the wording of the clause and its location in the verse varies significantly among the witnesses, which suggests that it was indeed borrowed from the Lukan parallel. The NA²⁸ puts the words in brackets indicating doubts about their authenticity.

¹ tc A few witnesses, especially of the Western text (D 33 it sy^s Ir^lat Or Eus^syr), do not contain 21:44. However, the verse is found in א B C L W Z Δ (Θ) 0102 ƒ^{1, 13} 565 579 700 1241 1424 M lat sy^c,p,h co. The NA²⁷ and NA²⁸ put this verse in brackets, which normally indicates some doubt as to its authenticity, but Metzger’s Textual Commentary claims that the committee concluded that the verse was an “accretion,” including it not because of authenticity but because of its longstanding role in the textual tradition (TCGNT 47). Some scholars see the verse as scribally borrowed from the parallel in Luke 20:18, but both the wording and word order are different enough that such an imperfect assimilation cannot account for the great variety of witnesses that have a uniform reading here. In light of the lack of adequate explanation for the rise of this verse as it is written, the longer reading should be preferred.
