1 tc The translation here follows the reading στήσητε (sthshte, “set up”) found in D W Θ Ë1 28 565 2542 it sys,p Cyp. The majority of mss here read τηρήσητε (thrhsete; א A L Ë13 33 Ï co) or τηρῆτε (thrhte; B 2427), both translated “keep.” It is hard to know which reading is best: On the one hand, τηρήσητε/τηρῆτε has much stronger external support, but στήσητε is a more difficult reading. What makes “keep” suspect is that it appears in two different forms, suggesting independent alterations of a difficult reading. Further, scribes may have been influenced by the preceding “commandment of God” to change the text toward “keep” (TCGNT 81), a common enough expression (cf. Matt 19:17; John 14:15; 1 Tim 6:1; 1 John 5:3; Rev 14:12). Thus, the more difficult reading is “set up.” Also, the more natural opposite of “reject” (ἀθεῖτε [aqeite], literally “you set aside”) is “set up.” However, the Western reading may have been influenced by Exod 6:4 or Heb 10:9, but this likelihood seems remote. Thus, “set up” is more likely to be the original wording of Mark here.
2 sn The statement he ran off naked is probably a reference to Mark himself, traditionally assumed to be the author of this Gospel. Why he was wearing only an outer garment and not the customary tunic as well is not mentioned. W. L. Lane, Mark (NICNT), 527-28, says that Mark probably mentioned this episode so as to make it clear that “all fled, leaving Jesus alone in the custody of the police.”
