Charles H. Spurgeon on Psalms 76:4

The mountains of prey. Why are they called the mountains of prey? There is a reference to the lairs of the lions in the mountains, whence they rush forth upon those who come that way, and tear them in pieces. In the same way the dwelling place of God was represented above under the title of a tabernacle or lair. Moreover, this is a mystic epithet of the mountains of Judah, by which it is hinted that the enemies who venture to approach that lair are wont to be torn in sunder: a terrible example of which had just been shown in the case of the Assyrian, there overthrown, torn, and spoiled. Compare Isa 31:4. Hermann Venema.
