And in this manner, it is explained in the liturgical poem "Who Knows One"—who merited to declare His blessed name in the world? "One, I know"—we, Israel, His people, the children of Abraham His beloved, merited this through the Exodus from Egypt. "Who knows two? Two tablets of the covenant"—which we merited because of the sufferings of exile, and through their giving, His blessed name was made known in His world. "One is our God in heaven and on earth." "Who knows three? The three patriarchs"—who are called by the name of Israel, and this is due to the Torah we received, which made His blessed name known in heaven and on earth. "Who knows four?" corresponds to the matriarchs: Sarah who separated Ishmael from us, and Rebecca who separated Esau, Rachel and Leah who built the house of Israel, and through them, we merited the three patriarchs, etc., as mentioned above. "Five, six"—correspond to the Written Torah and the Oral Torah. "Who knows seven?" corresponds to the Sabbath, which was given before the giving of the Torah only to Israel His people with love, and not to the nations of the world, and it prepared us for the receiving of the Torah. "Eight days of circumcision"—through which Abraham merited to be the father of all Israel who would receive the Sabbath and the Torah, etc. "Nine months of childbirth"—through which we are attributed to our forefathers, and this advantage is not found among the nations. "Ten commandments"—since they were given to us face to face, our faith in the Torah was strengthened in our hearts forever. "Who knows eleven? Eleven stars"—indicate the natural order of the world, which depends on the observance of the Torah and commandments, and therefore "I know" that we received the Torah. "Who knows twelve? Twelve tribes"—this is a great and additional good for Israel, as they correspond to the higher order of governance, upon which all good influences depend, and from which the natural order of the eleven stars is influenced by the merit of the Ten Commandments, etc. And all this we merited through the "Thirteen Attributes of Mercy," which everyone needs, even the holy patriarchs.
