This word is used only two Bible verses, 1 Kings 10:11-12. It probably means sandalwood sticks. The word is similar to “algum” of (2 Chronicles 2:8; 9:10-11) which is believed to mean sticks of algum trees.
In the Hebrew, this word occurs in the plural almuggim which seems to indicate that the wood was brought in planks, the name of a wood brought from Ophir to be used in the building of the temple, and for other purposes.
Some believe it was the white sandalwood of India (Santalum album), a native of the mountainous parts of the Malabar coasts. It is a fragrant wood, and is used in China for incense in idol-worship. Others think that it was more likely the Indian red sandalwood (Pterocarpus santalinus), a heavy, fine-grained wood, the Sanscrit name of which is valguka. It is found on the Coromandel coast and in Ceylon.
