Jeremiah 50:38

³⁸ A drouth is upon her waters; and they shall be dried up: for it is the land of graven images, and they are mad upon their idols.

Sparrow and swallow

In Psalm 84:3, 'a sparrow' signifies spiritual truth, and 'a swallow' signifies natural truth from which worship is performed.

⁷ And the unicorns shall come down with them, and the bullocks with the bulls; and their land shall be drenched with blood, and their dust made fat with fatness.
