To all my precious Rebbetzins and to all the good and kosher Daughters of Israel who are publicly sanctifying the name of Hashem. Our Father in Heaven is pleased with you, and the heavenly angels take pride in you. You resemble the Kohen Gadol who wore many beautiful and holy garments for the honor of Hashem. The Kohen atoned for the sins of Israel with his holy and pure garments, so too it is in our generation; women and precious girls who are wearing clothing for the honor of Hashem such as the shawl and respectable and holy head coverings are atoning for the generation. It's worth it therefore to stay strong in spite of the bit of insult and mocking you may receive for the sake of our Father in Heaven and for the sake of our Holy Torah and for the sake of Tzniut (modesty)!
If you could only see what incredible pleasure you are bringing to the Creator of The World you would be as happy as Miriam the prophetess with her drums. Sara Shnirer who was the epitome of modesty and concealment, who was totally faithful and connected to her Father in Heaven, had stones thrown at her because of this. She was not upset; rather she turned to Hashem and said, "With these stones, I will build for Your honor the Beit Yaakov School."
So it is the same with you, you holy and precious souls who are so beloved above. You are bringing joy to all the worlds with your modesty, head coverings, shawls, and extra coverings – done for the sake of Heaven with humility and happiness. With this we will build for our Father the righteous women's gallery in the Heavenly Beit Hamikdash.
I love you all with all my soul and I pray for you all 24 hours a day. My feet are in Teveria, but my heart is in Yerushalayim the Holy City.
Your Tehillim are protecting all of Israel. Waiting every moment for the complete and final redemption, G-d willing.
Your sister, Leah Kook
