Albert Barnes Commentary Micah 6:3

"O my people, what have I done unto thee? and wherein have I wearied thee? testify against me." — Micah 6:3 (ASV)

O My people - This one tender word, twice repeated, itself contains a whole volume of reproof. It sets before their eyes God’s choice of them of His free grace, and the whole history of His loving-kindness, so that they might be ashamed of their thanklessness and turn to Him. “Mine,” He says, “you are by creation, by Providence, by great deliverances and by hourly love and guardianship, by gifts of nature, the world, and grace; such things have I done for you; what against you? what evil have I done unto thee?” Thy foot did not swell these forty years (Deuteronomy 8:4), for He upholds them in all ways where He leads.

Wherein have I wearied thee? For His commandments are not grievous (1 John 5:3). Thou hast been weary of Me, O Israel, God says by Isaiah, I have not wearied thee with incense; thou hast wearied Me with thine iniquities (Isaiah 43:22–24).
