The tefilah of Adon Olam has been given much prominence. It was placed at the start of our daily Shacharis tefilah, it is recited by many nightly before going to bed, and we begin our Rosh HaShanah and Yom Kippur tefilos in the morning using a special nusach for this inspiring tefilah. In effect, we start and end our day with Adon Olam every day of the year and give it even more attention on Rosh HaShanah and Yom Kippur.

Bo’u sh’arav b’sodah, chatzeirosav bis’hilah; hodu lo, barchu sh’mo.

(Therefore) enter His gates with thankfulness (for the miracles), (and proceed into) His courtyard to express the praise of His greatness, (and) thank Him for the good He has done for you, and praise His Name (which represents His way of running the world to do good to us).

Mizmor l’sodah: Hariu LaShem kol ha’aretz.

A song of thanksgiving: Everyone on Earth should call out to Hashem (and rejoice in His kindness).

We begin Mizmor L’Sodah by calling out to the whole world to sing to Hashem.
