Kabbalah zu Bereschit 26:22

"And he removed from there, and dug another well..." (Beresheet 26:22). Rabbi Chiya opened the discussion with the verse, "and Hashem shall guide you continually, and satisfy your soul in drought, and make strong your bones" (Yeshayah 58:11). This verse had already been explained, but by this verse the faithful were strengthened, for it promises them the World to Come. "And Hashem shall guide you continually" in this world and the World to Come. "And Hashem shall guide you." Because he said, "And Hashem shall guide you," why add the word "continually (Heb. תָּמִיד)?" For this hints at the daily offering (lit. 'continue') made at dusk that receives its strength from underneath Yitzchak's arm. How do we know that? From David, as it is written, "He leads me in the paths of righteousness for His name's sake" (Tehilim 23:3). Just as the word "leads," spoken by David, means the illumination of the left, as it is written, "in the paths of Righteousness," which is a name of the Nukva when she shines from the left, here too when it says "guide," it alludes to the illumination of the left.
