by Rabbi Naftali SilberbergThe Amidah (pronounced ah-MEE-dah) is the central, critical section of Shacharit, Musaf, Minchah and Ma'ariv prayers, around which the other sections were built. In the times of the Temples, when full Tefillah services were not required, tefillah consisted of the Amidah only. The Amidah, which means "standing" in Hebrew, is a series of 12 requests (it is now thirteen as enumerated later in the article**) of G-d recited silently while standing at attention, as if before a king, introduced by three praises of G-d and capped by three thank-yous. Because of the eighteen sections, the amidah is also known as the Shmoneh Esrei, meaning "eighteen" in Hebrew (although it's really nineteen, because of one extra request added later**).
[On Shabbat, holidays and Rosh Chodesh, the musaf Amidah is fewer than nineteen blessings. The first three and last three blessings are the same as all the other times the Amidah is recited, however, the middle changes as appropriate to the special date.]
The first and last three blessings of the Amidah offer praise and thanksgiving to G-d. The middle thirteen, are devoted to all our requests.
The following list (of the middle thirteen) describes the main point of each of these blessings:
4. Knowledge and intelligence.
5. Awaken us to repent.
6. Atonement.
7. Redemption.
8. Cures for our illnesses.
9. Livelihood.
10. Ingathering of the Diaspora.
11. Return of Jewish courts and justice.
12. Elimination of evil. **(This is the 19th blessing which was added later.)
13. Support and reward the righteous.
14. Rebuilding Jerusalem.
15. Restore the royal Davidic House.
16. General request for G-d to hearken to our prayers.
These prayers contain standard liturgy, but should be imbued with your personal feelings and desires as you adopt each word to be your own. If you would like to add your own words, find the blessing which is closest to the nature of your request, and insert your private prayer. If your request doesn't match any of the above blessings, you can always add it to blessing #16.
