The black horse

“When the Lamb opened the third seal, I heard the third living creature say, ‘Come!’ I looked, and there before me was a black horse! Its rider was holding a pair of scales in his hand. Then I heard what sounded like a voice among the four living creatures, saying, ‘A quart of wheat for a day’s wages, and three quarts of barley for a day’s wages, and do not damage the oil and the wine!’” Revelation 6:5-6
The black horse here follows the red horse, representing war. The black horse is famine. The words we hear here indicate that following the war that encompasses the earth when the red horse is released, the world will once again undergo a period of mass economic inflation. A day’s wage for the average person will only be sufficient to buy a day’s worth of food.
This all points to a severe shortage of staple foods in the aftermath of world war, with crops either neglected as the nations fight against each other, or they will fail to grow as a consequence of a nuclear exchange, with the seasons and air clarity being affected. The scales in the hand of the horseman symbolise how food will be rationed out and measured by weight among the people who survive the war. But for the wealthy, there will still be the obsession over obtaining luxury food items (oil and wine). The disparity between rich and poor will continue to increase in those times.
