149. This is the meaning of, "seven complete Shabbatot" (Vayikra 23:15), WHICH MEANS THAT after seven Shabbatot have passed, the Holy King comes to unite with the Congregation of Yisrael, and the Torah is given. Then the King, ZEIR ANPIN, is adorned with the complete union, and the time of the Torah has come. All the trees that produce the firstfruits start singing, BECAUSE THEY DO SO BY THE ILLUMINATION OF THE UNION. What do they sing when THE FRUITS are gathered? "Hashem has established His throne in the heavens; and His kingdom rules over all" (Tehilim 103:19), AS THE THRONE, MALCHUT, IS BUILT AND ESTABLISHED IN THE HEAVENS, ZEIR ANPIN. THEN MALCHUT IS PERFECTED IN EVERY RESPECT, and it is written, "Your steadfast love, Hashem, is in the heavens" (Tehilim 36:6), WHICH MEANS THAT CHASSADIM FLOW FROM ZEIR ANPIN TO MALCHUT. And it is also written, "and all the trees of the field shall clap their hands" (Yeshayah 55:12), NAMELY, THE ILLUMINATION OF MALCHUT CALLED "FIELD" WILL CLAP HANDS. IN RELATION TO THIS UNION, RABBI SHIMON OPENED THE ARTICLE WITH THE VERSE, "THEN SHALL THE TREES OF THE WOOD SING FOR JOY" (I DIVREI HAYAMIM 16:33).
