Kabbalah su Osea 14:3

And this hey is obviously the verbal confession, and the secret of the word, "take with you words and return to Ad-nai, say to Him etc we will pay the bulls of our lips" (Hoshea 14:3). That obviously because the person who sins that person distances the hey from the vav, and separates YHV from H. And because of that the temple was destroyed and Israel was distanced from there, and was exiled among the peoples. And because of that whoever does teshuvah causes the Hey to return to the Vav, and redemption is dependent in this. And in this way all is dependent in teshuvah. As the olden ones said: "all the calculated ends have passed and the matter is only dependent on teshuvah [and good deeds] etc" (Sanhedrin 97b:14) - and this is the completion of the Name.
