[5:44] 1 tc Most mss ([D] L [W] Θ Ë13 33 Ï lat) read “bless those who curse you, do good to those who hate you, and pray for those who mistreat you,” before “those who persecute you.” But this is surely a motivated reading, importing the longer form of this aphorism from Luke 6:27-28. The shorter text is found in א B Ë1 pc sa, as well as several fathers and versional witnesses.
[5:45] 2 tn Grk “be sons of your Father in heaven.” Here, however, the focus is not on attaining a relationship (becoming a child of God) but rather on being the kind of person who shares the characteristics of God himself (a frequent meaning of the Semitic idiom “son of”). See L&N 58.26.
