On all the walls of the temple of Jerusalem, within and without, and also upon the doors, were carved cherubim and palms (1 Kings 6:29, 32). The same in the new temple, mentioned in Ezekiel 41:18-20. By "cherubim" is signified the Word (n. 239), and by "palms" Divine truths therein. That by "palms" are signified the Divine truths of the Word, and by "palms in their hands" confessions from them, may appear from its being commanded that:

At the feast of tabernacles they should take fruits of the tree of honor, and leaves of palms, and should be glad before Jehovah (Lev. 23:39-40). When Jesus went to Jerusalem to the feast, they took branches of palms, and went to meet Him, crying, Blessed is He that cometh in the name of the Lord (John 12:12-13). By which was signified confession from Divine truths concerning the Lord. "The palm" signifies Divine truth also in David:

The just shall flourish like the palm, those that be planted in the house of Jehovah shall grow, he shall spring up in the courts of our God (Ps. 92:12-13). In like manner in other places. Because Jericho was a city near Jordan, and by "the river Jordan" was signified that which is first in the church, and this is the Divine truth, such as it is in the sense of the letter of the Word, therefore it was called "the city of palms" (Deut. 34:3; Judg. 1:16; 3:13). For Jordan was the first boundary or entrance into the land of Canaan, and by the land of Canaan is signified the church.
