Grateful at such unlooked-for grace being promised to Israel, Micah breaks forth into praises of Jehovah.
passeth by the transgression - not conniving at it, but forgiving it; leaving it unpunished, as a traveler passes by what he chooses not to look into (Pro 19:11). Contrast Amo 7:8, and “mark iniquities,” Psa 130:3.
the remnant - who shall be permitted to survive the previous judgment: the elect remnant of grace (Mic 4:7; Mic 5:3, Mic 5:7, Mic 5:8).
retaineth not ... anger - (Psa 103:9).
delighteth in mercy - God’s forgiving is founded on His nature, which delights in loving-kindness, and is averse from wrath.
