Signs of the times
In Old Testament days, God would withdraw His loving care and protection from Israel when the people rejected His truths and "walked in the counsels and in the imagination of their evil heart." (Jeremiah 7:24) Left to their own resources, they often faced plagues ("serious and prolonged sicknesses"), drought, famine and wars -- sometimes locusts -- all of which would increase in end times.

You shall lend to many nations, but you shall not borrow. And the Lord will make you the head and not the tail.... if you heed the commandments of the Lord your God."“But... if you do not obey the voice of the Lord your God... all these curses will come upon you and overtake you....

The Lord will change the rain of your land to powder and dust..."Locusts shall consume all your trees and the produce of your land. The alien who is among you shall rise higher and higher above you, and you shall come down lower and lower. He shall lend to you, but you shall not lend to him; he shall be the head, and you shall be the tail....
"If you do not carefully observe all the words of this law that are written in this book [remember, the Levitical laws were fulfilled in Christ, but the moral law is as relevant now as then], that you may fear this glorious and awesome name, THE LORD YOUR GOD, then the Lord will bring upon you and your descendants extraordinary plagues—great and prolonged plagues—and serious and prolonged sicknesses. ...."
