"I have overthrown some of you, As when God overthrew Sodom and Gomorrah, And you were like a burning stick plucked out of the fire; Yet you haven't returned to me," says Yahweh.
Amos 4:6-11 have recounted the seven great disasters through which Israel had passed, ending in the same plaintive cry every time.  "Yet have ye not returned unto me, saith Jehovah."
