The Hebrew name Ithamar (אִיתָמָר) is generally understood to mean "coast of the palm-tree" or "island of palms," from iy (coast/island) and tamar (palm tree, H8558). It is the name of Aaron's youngest son, who became the ancestor of a significant priestly line in Israel.
Ithamar was the fourth son of Aaron and Elisheba (Exodus 6:23), ordained as priest alongside his brothers (Exodus 28:1). He supervised the construction contributions to the Tabernacle (Exodus 38:21) and oversaw the Gershonite and Merarite Levites (Numbers 4:28, 33). His line continued through Eli the priest. When David organized the priests, half the priestly courses descended from Ithamar's line (1 Chronicles 24:4–6). His name evokes beauty and life — palms symbolize the righteous flourishing in God's presence (Psalm 92:12).
