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.
8 The promise they will be comforted is the first of several “reversals” noted in these promises. The beatitudes and the reversals that accompany them serve in the sermon as an invitation to enter into God’s care, because one can know God cares for those who turn to him.
9 Those who hunger are people like the poor Jesus has already mentioned. The term has OT roots both in conjunction with the poor (Isa 32:6–7; 58:6–7, 9–10; Ezek 18:7, 16) or by itself (Ps 37:16–19; 107:9).
