Their falling is compared to the effect a powerful wind has on a fig tree; the shaking prompts one fig after the other to fall till there are no figs left in the tree (see also Isaiah 34:4). Similarly, at the opening of the sixth seal, the constellations God placed in the sky come unstuck from their positions so that they no longer twinkle in the night sky.
13 and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale.
