Smith's Bible Dictionary (1863)
The Hebrew words thus translated denote some species of antelope, probably the Gazella arabica of Syria and Arabia. The gazelle was allowed as food, (12:15,22) etc.; it is mentioned as very fleet of foot, (2 Samuel 2:18; 1 Chronicles 12:8) it was hunted, (Isaiah 13:14; Proverbs 6:5) it was celebrated for its loveliness. (Song of Solomon 2:9,17; 8:14)
Hastings' Dictionary of the Bible (1898)
ROE, ROE'BUCK (beauty), an animal especially fleet of foot, 2 Sam 2:18; 1 Chr 12:8, and elegant in form. Roe, or Gazelle. (Gazella Dorcas. After Wood.) Song 2:9, 2 Sam 21:17; Am 8:14. The gazelle (Gazella dorcas) satisfies these and all other requirements, and is still very abundant in Palestine and adjacent regions. The Jews might use the roe as food, Deut 12:15, Josh 11:22; it was hunted, Isa 13:14:" it is amiable, affectionate, and loving, by
universal testimony," Prov 5:19; and it has ever been admired for its beauty, which is the meaning of its Hebrew name. "Tabitha" or "Dorcas" means "a gazelle." Acts 9:36.
