Rabbi Rahumai sat and expounded: What is the meaning of the verse (Deuteronomy 33:23), "The filling is God's blessing, possessing the Sea and the South"? This means that wherever we find the letter ב it is blessed. This is the Filling referred to in the verse, "The filling is God's blessing." From there it nourishes those who need it.
It was from this Filling that God sought advice. What example does this resemble? A king wanted to build his palace among great cliffs. He mined into the bedrock and uncovered a great spring of living water.
The king then said, "Since I have flowing water, I will plant a garden. Then I will delight in it, and so will all the world." It is therefore written (Proverbs 8:30), "I was with Him as a craftsman, I was His delight for a day, a day, frolicking before him at every time." The Torah is saying, "For two thousand years I was in the bosom of the Blessed Holy One as His delight."
The verse therefore says, "a day, a day." Each day of the Blessed Holy One is a thousand years, as it is written (Psalm 90:4), "A thousand years in Your eyes is as but yesterday when it is passed." From then on, it is at times, as the verse states, "...at every time." The rest is for the world.
It is thus written (Isaiah 48:9), "I will breathe out My praise through My nose for you." What is the meaning of "My praise"? As it is written (Psalm 145:2), "A praise of David, I will raise You high..." Why is this a praise?
Because I will "raise You high." And what is this elevation? Because "I will bless Your name for the world and forever."
