다니엘 1:6의 Kabbalah

"Jacob shall not now be ashamed, neither shall his face now grow pale; when he sees his children, the work of My hands, in the midst of him, sanctifying My name" (Isaiah 29:22-23). Who are "his children, the work of My hands?" They are Hananiah, Mishael, and Azariah. "Jacob shall not now be ashamed:" What is Jacob doing here? For it is written, "These were among the descendants of Judah: Daniel, Hananiah, Mishael, and Azariah" (Daniel 1:6). They are referred to as scions of Judah. As a result, it should read: 'Judah shall not now be ashamed.' Why then does it state, "Jacob shall not now be ashamed?"
