The phrase "אני לדודי ודודי לי" (Ani L’dodi V’dodi Li) translates to "I am my beloved’s, and my beloved is mine." It comes from Shir HaShirim (Song of Songs) 6:3 and is often interpreted as an expression of the relationship between the Jewish people and G-d, where the Jewish people are "my beloved" (Hashem's beloved) and Hashem is "mine."
In the context of the month of Elul, this phrase is seen as symbolic of the closeness between Hashem and the Jewish people during this time of repentance and spiritual reflection. The initial letters of the words "אני לדודי ודודי לי" spell אלול (Elul), further linking the phrase to the themes of love, return, and connection that define this period. It reflects the reciprocal nature of the relationship: just as we turn toward Hashem in repentance and love, Hashem draws closer to us with mercy and forgiveness.
