The Hebrew/Aramaic verb atah means to come or to arrive — often used of persons approaching or of future events arriving. In prophetic poetry it carries eschatological weight, describing the coming of God, the coming Day of the LORD, or the arrival of Messianic fulfillment.
In Deuteronomy 33:2, atah describes God 'coming' with ten thousands of holy ones — a theophanic arrival of divine majesty for His people. Isaiah 21:12 uses it in the mysterious watchman oracle: 'Morning comes (atah), and also the night.' The verb marks the inexorable movement of divine history toward its appointed end. Every 'coming' of God in the Old Testament prefigures the ultimate atah — the Incarnation and the return of Christ.
