The Hebrew word aviv refers to grain that has reached the stage of being tender and formed but not yet fully ripened — the fresh green ears of barley or wheat in early spring. By metonymy, aviv became the name for the first month of the Hebrew religious calendar (corresponding roughly to March-April), when the barley would be in this state. God commanded the Exodus to mark this month as the beginning of months (Exodus 12:2; 13:4). It is the month of Passover — the month of Israel's birth as a nation.
Aviv (spring grain) is a symbol of new life, new beginnings, and divine timing. The Exodus happened in the month of Aviv — not by accident, but because spring itself is a sermon on resurrection. Dead seeds sprout; frozen earth thaws; what seemed finished comes to life. Passover in Aviv prefigured Christ's death and resurrection — which also occurred in this month. The Song of Songs celebrates the arrival of spring (aviv) as the season of the Beloved's coming (Song of Songs 2:11–13). Every spring is a reminder: God makes all things new. The city of Tel Aviv takes its name from this word.
