Matthew Poole and continuators on Jeremiah 2:15

15 The young lions roared upon him, and yelled , and they made his land waste: his cities are burnt without inhabitant .

Understand the Assyrians, Babylonians and Egyptians, &c. called Lions from their fierceness, and young from their strength, see this chap. 4.7. and 50.17.

Noting the terrible voice, that the Lion puts forth either in the seizing the prey, some say in sport, Lam. 2.7. or the devouring it, Isa. 5.29. a Metaphor noting the cruelty of the Enemy, Psal. 74.4.

i. e. So consumed, and wasted, that they are uninhabitable, or shortly shall so consume, and wast them, see ver. 14.

Marginal references: Heb. gave out their voice.
