Psalms 104:18 - Matthew Poole's English Annotations on the Holy Bible

So he passeth from the rain to other works of God's 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 rendered, And the high hills, (understand, are satisfied, which is expressed Psalms 104:16, 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.
