If one has a dream which makes him sad he should go and have it interpreted in the presence of three. He should have it interpreted! Has not Rav Ḥisda said: A dream which is not interpreted is like a letter which is not read? — Say rather then, he should have a good turn given to it in the presence of three. . . .
Psalm 67 is a priestly blessing for all the peoples of the earth to be sustained by the earth’s harvest (yevulah), and it is a petition that all humanity recognize the divine nature (Elohim) illuminating the world. Composed of seven verses, the psalm is often visually depicted as a seven branched menorah. There are 49 words in the entire psalm, and in the Nusaḥ ha-ARI z”l there is one word for each day of the Sefirat haOmer. Similarly, the fifth verse has 49 letters and each letter can be used as a focal point for meditating on the meaning of the day in its week in the journey to Shavuot, the festival of weeks (the culmination of the barley harvest), and the festival of oaths (shevuot) in celebration of receiving the Torah. Many of the themes of Psalm 67 are repeated in the prayer Ana b’Koaḥ, which also has 49 words, and which are also used to focus on the meaning of each day on the cyclical and labyrinthine journey towards Shavuot. . . .
