His mother is Batsheba, NAMELY, THE SECRET OF MALCHUT CALLED BATSHEBA (LIT. 'DAUGHTER OF SEVEN'). We have learned that it is written, "The proverbs of Solomon. A wise son makes a glad father: but a foolish son is the grief of his mother" (Mishlei 10:1). Assuredly he is the grief of his mother. See what is written, "A wise son makes a glad father," MEANING so long as the son walks in a straight path, and he is wise, he "makes a glad father." This refers to the Holy King above, MEANING ZEIR ANPIN, as it is written, "Makes a glad father" without specifying, WHICH POINTS TO THE FATHER ABOVE. AND IF this son is on a stumbling manner, it is written, "But a foolish son is the grief of his mother." For sure it is the grief of his mother, referring to the Congregation of Yisrael, DENOTING MALCHUT. The secret of the matter is the words, "And for your transgressions was your mother put away" (Yeshayah 50:1), WHO IS MALCHUT.
