The Hebrew word Ethanim (אֵיתָנִים) is the ancient Canaanite name for the seventh month of the Hebrew calendar — later known as Tishri (September–October). The name is related to ethan (H386, perpetual/ever-flowing) and may refer to the permanent streams that flow during this season after the summer rains begin.
Ethanim corresponds to the most sacred season of the entire Hebrew calendar — the month containing Rosh Hashanah (Feast of Trumpets), Yom Kippur (Day of Atonement), and Sukkot (Feast of Tabernacles). Solomon's Temple was dedicated during this month (1 Kings 8:2), symbolizing the culmination of God's redemptive purposes. The name's connection to "permanent streams" evokes the imagery of living water — God's presence and Spirit flowing perpetually to His people.
