3:9-15 That power which is an instrument of unrighteousness, will justly be brought down and broken. What is got and kept wrongfully, will not be kept long. Some are at ease, but there will come a day of visitation, and in that day, all they are proud of, and put confidence in, shall fail them. God will inquire into the sins of which they have been guilty in their houses, the robbery they have stored up, and the luxury in which they lived. The pomp and pleasantness of men's houses, do not fortify against God's judgments, but make sufferings the more grievous and vexatious. Yet a remnant, according to the election of grace, will be secured by our great and good Shepherd, as from the jaws of destruction, in the worst times.

Ashdod—put for all Philistia. Convene the Philistine and the Egyptian magnates, from whom I have on various occasions rescued Israel. (The opposite formula to "Tell it not in Gath," namely, lest the heathen should glory over Israel).

upon the mountains of Samaria—on the hills surrounding and commanding the view of Samaria, the metropolis of the ten tribes, which was on a lower hill (Am 4:1; 1Ki 16:24). The mountains are to be the tribunal on which the Philistines and Egyptians are to sit aloft to have a view of your crimes, so as to testify to the justice of your punishment (Am 3:13).
tumults—caused by the violence of the princes of Israel in "oppressions" of the poor (Job 35:9; Ec 4:1).
