Psalms 104:18

“The high hills are a refuge for the wild goats - Still keeping up the description of animated nature - the carrying out of the work of creation. The idea is, that nature is full of life. Even the most inaccessible places - the rocks - the high hills - have their inhabitants. Where man cannot climb or dwell, there are abodes of animals which God has made to dwell there, and which find there a refuge - a shelter - a home. On the word used here, and rendered “wild goats,” see the notes at Job 39:1. The word occurs elsewhere only in 1 Samuel 24:2. And the rocks for the conies - The word here “employed” - שׁפן shâphân - denotes a quadruped that chews the cud, in the manner of a hare Leviticus…”

“the wild goats: The yaal, is the ibex, or rock goat, so called from alah, to ascend, because it is famous for mounting to the tops of the highest rocks. Its general appearance is that of the tame goat, of a dusky brown colour; but the male is larger, with long horns, bending backwards. Sa1 24:2; Job 39:1 the conies: Deu 14:7; Pro 30:26 Psalms 104:19”
