General Information:

This continues God's declaration concerning the people of Judah.

A declaration

"This is what Yahweh declares"

of the lioness and the lion, the viper and fiery flying serpent

This refers to these types of animals in general. Alternate translation: "where lionesses and lions dwell, and where there are vipers and serpents" (See: rc://en/ta/man/translate/figs-genericnoun)

fiery flying serpent

Here the word "fiery" probably refers to the serpent's poisonous bite and the word "flying" refers to its quick movements. See how you translated this in Isaiah 14:29.
