fallow deer

Boyd’s Bible Dictionary:

(yellowish brown). The bubalis or African deer (Deut. 14:5; 1 Kings 4:23). Some say the Arabian wild ox.

Concise Bible Dictionary:

What species of deer is referred to under this name is not known. The only description of it in scripture is that it was a clean animal that the Israelites might eat, and that it was supplied to the table of Solomon (Deut. 14:5; 1 Kings 4:23). The Hebrew name seems to imply that it was some deer of a “red” color.
