Here's a small digg into the etymological history to understand their symbology.
.
phoenix (n.)
Etymology from Latin phoenix, from Greek phoinix, the mythical bird of Arabia which flew to Egypt every 500 years to be reborn,
it also meant "the date" (fruit and tree), and "Phoenician," literally "purple-red," perhaps a foreign word (Egyptian has been suggested),
or from phoinos "blood-red." The exact relation and order of the senses in Greek is unclear.
Phoenician (n.)
from Latin Phoenice, from Greek Phoinike "Phoenicia" (including Carthage), perhaps literally "land of the purple"
(i.e., source of purple dye, the earliest use of which was ascribed to the Phoenicians by the Greeks). Identical with phoenix
The word φοῖνιξ phoînix meant variably "Phoenician person", "Tyrian purple, crimson" or "date palm" and is attested with all three meanings already in Homer.
(The mythical bird phoenix also carries the same name, but this meaning is not attested until centuries later.)
The word may be derived from φοινός phoinós "blood-red", itself possibly related to φόνος phónos "murder".
The folk etymological association of Φοινίκη with φοῖνιξ mirrors that in Akkadian, which tied kinaḫni, kinaḫḫi "Canaan" to kinaḫḫu "red-dyed wool".
The land was natively known as knʿn (compare Eblaite ka-na-na-um, phn|ka-na-na) and its people as the knʿny. In the Amarna letters of the 14th century BC,
people from the region called themselves Kenaani or Kinaani, in modern English understood as/equivalent to Canaanite. Much later, in the sixth century BC,
Hecataeus of Miletus writes that Phoenicia was formerly called χνα khna, a name that Philo of Byblos later adopted into his mythology as his
eponym for the Phoenicians: "Khna who was afterwards called Phoinix". The ethnonym survived in North Africa until the fourth century AD Punic Languages.
The name "Phoenician" is by convention given to inscriptions beginning around 1050 BC, because Phoenician, Hebrew, and other Canaanite dialects were
largely indistinguishable before that time.
The religious practices and beliefs of Phoenicia were cognate generally to their neighbours in Canaan, which in turn shared characteristics common throughout
the ancient Semitic world. "Canaanite religion was more of a public institution than of an individual experience." Its rites were primarily for city-state purposes;
payment of taxes by citizens was considered in the category of religious sacrifices. Phoenicians were known for being very religious, several of its reported
practices include temple prostitution, and child sacrifice.
"Tophets" built "to burn their sons and their daughters in the fire" are condemned by God in Jeremiah 7:30-32, and in 2nd Kings 23:10 (also 17:17).
Notwithstanding these and other important differences, cultural religious similarities between the ancient Hebrews and the Phoenicians persisted.
Canaanite religious mythology does not appear as elaborated compared with existent literature of their cousin Semites in Mesopotamia. In Canaan the supreme
god was called El ( "god"). The son of El was Baal ("master", "lord"), a powerful dying-and-rising storm god. Other gods were called by royal titles, as in Melqart
meaning "king of the city", or Adonis for "lord". (Such epithets may often have been merely local titles for the same deities.) On the other hand, the Phoenicians,
notorious for being secretive in business, might use these non-descript words as cover for the secluded name of the god, known only to a select few initiated into
the inmost circle, or not even used by them, much as their neighbors and close relatives the ancient Israelites/Judeans sometimes used the honorific
Adonai (Hebrew "My Lord").
