Boyd’s Bible Dictionary:
(oz). Written “Lign (wood) Aloes” (Num. 24:6). A costly and sweet smelling wood of India, much prized in the East (Psa. 45:8; Prov. 7:17; Song of Sol. 4:14; John 19:39).
Concise Bible Dictionary:
The passages where aloes are mentioned clearly show that it was a highly odoriferous tree or wood, but it cannot be identified with certainty (Num. 24:6; Psa. 45:8; Prov. 7:17; Song of Sol. 4:14). The ἀλόη was one of the perfumes which Nicodemus brought with which to embalm the body of our Lord (John 19:39). The common aloes being of a disagreeable odor makes the identification of the above more difficult. The agallochum is the aloe-wood of more recent times.
