On the first of Tishrei, G‑d completed all the acts of creation, for it was on this day that man was created, according to the opinion of R. Eliezer (Rosh Hashanah 11 a) who maintains that the world was created in the month of Tishrei.

According to R. Eliezer, the Patriarchs - who represent the beginning of the world after the sins of the preceding generations - were all born in the month of Tishrei.

On Rosh Hashanah, Sarah, Rachel, and Chanah were granted Divine remembrance, for they were all barren until G‑d remembered them that day with the promise of children.

On Rosh Hashanah, Joseph was freed from the Egyptian prison where he had been held for twelve years and it was from then that his light began to shine.

On Rosh Hashanah, the bondage of our ancestors in Egypt ceased, and their redemption began.

On Rosh Hashanah, Adam was created.
In the first hour of the day G‑d thought of creating man.
In the second hour He consulted with the ministering angels.
In the third hour He gathered the dust from which man was made.
In the fourth hour He prepared it.
In the fifth hour He formed it.
In the sixth hour He stood man on his feet.
In the seventh hour He placed a soul within him.
In the eighth hour He brought him into Gan Eden.
In the ninth hour He commanded him not to partake of the tree which imparted knowledge.
In the tenth hour man violated this command.
In the eleventh hour he was judged.
In the twelfth hour he was forgiven by G‑d.

G‑d said to him: "You are a sign unto your children. Just as you were brought before Me to be judged, and you emerged forgiven, so too are your children destined to be brought before Me on this day to be judged, and they will also emerge forgiven" (Pesikta d'Rav Kahana).
