57 Grk “And.” Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the narrative.
58 Grk “his”; the referent (Jesus) has been specified in the translation for clarity.
59 The issue of whether Jesus had brothers (siblings) has had a long history in the church. Epiphanius, in the 4th century, argued that Mary was a perpetual virgin and had no offspring other than Jesus. Others argued that these brothers were really cousins. Nothing in the text suggests any of this. See also John 7:3.
60 Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation.
