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.
