At the second seal, the rider of the red horse was permitted to take away what from the earth?

Answer: Peace

The bright red horse's rider was granted permission to take away peace from the earth and to make men slay one another.

“And when the Lamb opened the second seal, I heard the second living creature say, “Come!” Then another horse went forth. It was bright red, and its rider was granted permission to take away peace from the earth and to make men slay one another. And he was given a great sword.”— Revelation 6:3-4 (BSB)
