The gazelle (Gazella dorcas) is found in great numbers in Palestine. "Among the gray hills of Galilee it is still 'the roe upon the mountains of Bether,' and I have seen a little troop of gazelles feeding on the Mount of Olives close to Jerusalem itself" (Tristram).
The Hebrew word ('ayyalah) in Pr. 5:19 thus rendered (R.V., "doe"), is properly the "wild she-goat," the mountain goat, the ibex. (See 1 Sam. 24:2; Ps. 104:18; Job 39:1.)
