Jamieson, Fausset and Brown on Micah 2:7

7. O thou ... named the house of Jacob--priding thyself on the name, though having naught of the spirit, of thy progenitor. Also, bearing the name which ought to remind thee of God's favors granted to thee because of His covenant with Jacob.

is the Spirit of the Lord straitened?--Is His compassion contracted within narrower limits now than formerly, so that He should delight in your destruction (compare Psa 77:7-9; Is 59:1, 2)?

are these his doings?--that is, Are such threatenings His delight? Ye dislike the prophets' threatenings (Mi 2:6): but who is to blame? Not God, for He delights in blessing, rather than threatening; but yourselves (Mi 2:8) who provoke His threatenings [Grotius]. Calvin translates, "Are your doings such as are prescribed by Him?" Ye boast of being God's peculiar people: Do ye then conform your lives to God's law?

do not my words do good to him that walketh uprightly--Are not My words good to the upright? If your ways were upright, My words would not be threatening (compare Psa 18:26; Mt 11:19; Joh 7:17).
