Amos 8:9

It shall come to pass, most certainly it will be, in that day, when God begins to execute these his just and severe judgments on the ten tribes. I will cause; the great, just, holy, and terrible God, who is provoked by these sins, and hath denounced these judgments, my hand shall be evident in it. The sun; literally, say some, but erroneously; by sun I understand rather the settled state of their prosperity under their present government in the house of Jehu; or it may refer particularly to their king and court, which Jeroboam at his death left like the sun at noon in the height of their glory, as all know who know the history of those times. To go down at noon; so Israel's sun did as at noon set under the dark cloud of home-bred conspiracies and civil wars by Shallum, Menahem, Pekah, and Hoshea, till the midnight darkness drew on by Pul, Tiglath-pileser, and Shalmaneser. I will darken; bring a thick cloud of troubles and afflictions. The earth; the common people, the whole body of the nation; so the sun speaks the royalty, nobility, and great ones of this kingdom, by an allusion well known in Scripture, and the earth speaks the common sort of people; and all are here threatened. In the clear day; when they did think (as in Jeroboam's time) all was safe, sure, and well settled, far from the night of sorrow and trouble, then will God bring all this he threateneth upon them.
