The almug is a valuable wood that King Solomon imported to build pillars in the temple and to make harps for the temple musicians (1 Kings 10:11–12). This wood was brought by ship from Ophir to Ezion-geber, a port near Elath. Today, scholars think Ophir might have been in Arabia, India, or East Africa near Mozambique. The word "algum" in 2 Chronicles 2:8 probably refers to the same type of wood.
The scientific name of the almug tree is Pterocarpus santalinus.
