1 Here δέ (de) has not been translated.
2 Or “up a mountain” (εἰς τὸ ὄρος, eis to oros). The expression up the mountain here may be idiomatic or generic, much like the English “he went to the hospital” (cf. 15:29), or even intentionally reminiscent of Exod 24:12 (), since the genre of the Sermon on the Mount seems to be that of a new Moses giving a new law.
3 Here καί (kai) has been translated as “then” to indicate the implied sequence of events within the narrative.
4 Grk “And opening his mouth he taught them, saying.” The imperfect verb ἐδίδασκεν (edidasken) has been translated ingressively.
5 The term Blessed introduces the first of several beatitudes promising blessing to those whom God cares for. They serve as an invitation to come into the grace God offers.
6 The poor in spirit is a reference to the “pious poor” for whom God especially cares. See Ps 14:6; 22:24; 25:16; 34:6; 40:17; 69:29.
7 The present tense (belongs) here is significant. Jesus makes the kingdom and its blessings currently available. This phrase is unlike the others in the list with the possessive pronoun being emphasized.
