Ecclesiastes 12:5

Also when [the old] are afraid of danger from that which is high, and fears are in the way, and the almond tree [their white hair] blooms, and the grasshopper [a little thing] is a burden, and desire and appetite fail, because man goes to his everlasting home and the mourners go about the streets or marketplaces.

Jeremiah 1:11

Moreover, the word of the Lord came to me, saying, Jeremiah, what do you see? And I said, I see a branch or shoot of an almond tree [the emblem of alertness and activity, blossoming in late winter].

Genesis 43:11

And their father Israel said to them, If it must be so, now do this; take of the choicest products in the land in your sacks and carry down a present to the man, a little balm (balsam) and a little honey, aromatic spices and gum (of rock rose) or ladanum, pistachio nuts, and almonds.

The Almond (Prunus dulcis, syn. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill.) is a species of tree of the genus Prunus, belonging to the subfamily Prunoideae of the family Rosaceae and native to the Middle East. Within Prunus, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by the corrugated seed shell.

Almond is also the name of the edible and widely cultivated nut of this tree. Although popularly referred to as a nut, the almond fruit's seed is botanically not a true nut, but the seed of a drupe (a botanic name for a type of fruit).

1 Kings 10:11-12

The navy also of Hiram brought from Ophir gold and a great plenty of almug (algum) wood and precious stones.Of the almug wood the king made pillars for the house of the Lord and for the king's house, and lyres also and harps for the singers. No such almug wood came again or has been seen to this day.

2 Chronicles 2:8; 9:10-11

Send me also from Lebanon cedar, cypress, and algum timber, for I know your servants can skillfully cut timber in Lebanon; and my servants will be with your servants...
The servants of Huram and [those] of Solomon, who brought gold from Ophir, also brought algum trees and precious stones. The king made of the algum trees terraces or walks to the house of the Lord and to the king's palace, and lyres and harps for the singers; none such had ever been seen before in the land of Judah.

It was used, together with cedar and pine, in the construction of Solomon's Temple including the crafting of musical instruments for use in the Temple. Likely the wood was brought by the ships of Tarshish, sent from the Red Sea port of Ezion-Giber, from the distant country of Ophir, and was very valuable.

The botanical identity of algum is not known for certain, though some references suggest it may be juniper (Juniperus). Several species of juniper occur in the Middle East region, including Juniperus excelsa (Greek Juniper), Juniperus foetidissima (Stinking Juniper), Juniperus phoenicea (Phoenician Juniper), and Juniperus drupacea (Syrian Juniper).

Red acacia (Acacia seyal; also known as Shittim wood or Shittim tree) is a thorny, 6-10 m (20-30 ft) high tree with a greenish or reddish bark. At the base of the 3-10 cm (1-4 in) feathery leaves there are two straight, light grey thorns. The blossoms form round, bright yellow clusters approximately in 1.5 cm (0.5 in) diameter, growing to 7-20 cm (3-8 in) long.

It is distributed from Egypt to Kenya and west Senegal. In the Sahara, it often grows in damp valleys.

It appears in the Bible as the Hebrew "shittah" believed to be shittim wood which is of this species.
