Haggai’s fourfold list is a classic merism, where two extremes are mentioned to indicate everything in between. By naming the extremes, the prophet signals the whole. In other words, God is not shaking one part of creation but everything. The entire cosmos is included in the scope of his coming intervention.1
6 For thus says the LORD of hosts: Yet once more, in a little while, I will shake the heavens and the earth and the sea and the dry land.
