(Heb. tamar), the date-palm characteristic of Palestine. It is described as “flourishing” (Ps. 92:12), tall (Cant. 7:7), “upright” (Jer. 10:5). Its branches are a symbol of victory (Rev. 7:9). “Rising with slender stem 40 or 50, at times even 80, feet aloft, its only branches, the feathery, snow-like, pale-green fronds from 6 to 12 feet long, bending from its top, the palm attracts the eye wherever it is seen.” The whole land of Palestine was called by the Greeks and Romans Phoenicia, i.e., “the land of palms.” Tadmor in the desert was called by the Greeks and Romans Palmyra, i.e., “the city of palms.” The finest specimens of this tree grew at Jericho (Deut. 34:3) and Engedi and along the banks of the Jordan. Branches of the palm tree were carried at the feast of Tabernacles (Lev. 23:40). At our Lord’s triumphal entrance into Jerusalem the crowds took palm branches, and went forth to meet him, crying, “Hosanna: Blessed is the King of Israel that cometh in the name of the Lord” (Matt. 21:8; John 12:13).

Palm Tree
Palm trees in Scripture mostly appear as decoration in holy places. Solomon’s builders carved the walls of the house “with carved figures of cherubims and palm trees and open flowers,” then overlaid them with gold. Ezekiel, in his vision of a new temple, sees palm trees on the posts of a gateway. Near the end of the Bible the picture moves from carved wood to a crowd: a great multitude from every nation stands before the throne, “clothed with white robes, and palms in their hands.” Start with 1 Kings 6:29-35, then turn to Revelation 7:9.

And he carved all the walls of the house round about with carved figures of cherubims and palm trees and open flowers, within and without.
The two doors also were of olive tree; and he carved upon them carvings of cherubims and palm trees and open flowers, and overlaid them with gold, and spread gold upon the cherubims, and upon the palm trees.
And he carved thereon cherubims and palm trees and open flowers: and covered them with gold fitted upon the carved work.
Ezekiel
And there were narrow windows to the little chambers, and to their posts within the gate round about, and likewise to the arches: and windows were round about inward: and upon each post were palm trees.
Revelation
After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
