A parenthesis. As in Jeremiah 7:16, all intercession is forbidden, and for this reason. Prayer for others for the forgiveness of their sins avails only when they also pray. The cry of the people now was that of the guilty smarting under punishment, not of the penitent mourning over sin.
This passage, like Isaiah 1:12, rebukes the inconsistency of Judah’s public worship of Yahweh with their private immorality and preference for idolatry. Translate it: “What hath My beloved in My house to practice guile there? The great men and the holy flesh (i. e., the sacrifices) shall pass away from thee.”
The “goodly” or “shapely fruit,” signifies the righteousness and faith which ought to have been the result of Israel’s possession of extraordinary privileges. The tree did not bear this fruit, and God now destroys it by a thunderstorm.
