it is customary to read this psalm from a page that uses the words to form a menorah, for it has (without the 4-word introduction of “for the musician of the songs, a psalm, a song:”) 49 words within it. the 49 corresponds to the sefirat haOmer, of course, but also to the 49 named parts of the menorah: 22 cups, 9 flowers, 11 buttons and 7 lamps.
for the musicians of the songs, a psalm, a song:
may G’d favor us and bless us; may he shine His countenance on us, selah!
–to make Your ways known in the world, and Your redemption among all the nations.
the nations will give thanks to You, G’d; the nations will give thanks to you–all of them.
the nations will rejoice and sing for You will judge the people with fairness, and You will guide the kingdoms on earth, selah!
the nations will give thanks to You, G’d; the nations will give thanks to You–all of them–that the earth has given forth its yield, and that G’d, our G’d, will bless us.
may G’d bless us and may all from the ends of the earth fear Him.
those of you who want to try something a little more kabbalistic might want to follow the way of Reb Nachman and meditate on 1 word of the Psalm (hebrew) each night. as there are 49 words, there are 49 meditations.
most sefardim and many ashkenazim follow this with the prayer ‘ana b’koach’.
