Matthew Poole and continuators on Psalms 104:18

18 The high hills are a refuge for wild goats, and the rocks for the conies .

So he passeth from the rain to other works of Gods Providence, as that God hath made suitable and sufficient provision for the security of these Creatures against their Persecutors. Although this Verse also may have a reference to the former work, and the barren and rocky Hills may be mentioned as receiving benefit by the rain, and it may be thus rendred, And the high hills (understand, are satisfied, which is expressed v. 16. and may very well be carried hither) which (that Particle being frequently understood) are a refuge for wild goats, and the rocks (understand out of the former branch, according to the usual manner, which are a refuge) for the conies, or, as others translate this word, for the mountain-mice.
