Easton's 1897 Bible Dictionary:

Hart
(Heb. 'ayal), a stag or male deer. It is ranked among the clean
animals (Deut. 12:15; 14:5; 15:22), and was commonly killed for
food (1 Kings 4:23). The hart is frequently alluded to in the
poetical and prophetical books (Isa. 35:6; Cant. 2:8, 9; Lam.
1:6; Ps. 42:1).
