Almug was a costly wood brought from Ophir for the temple and other royal purposes. It was also called algum and was used for musical instruments.
Almug is associated with Solomon’s temple, his house, and the construction of instruments. The plural form in Hebrew may indicate that it was brought in planks.
The exact species is uncertain. It has been identified with white sandalwood from India or with red sandalwood from the Coromandel coast and Ceylon. The proposed woods are fragrant, heavy, and fine-grained.
