זוהר שמות — דף קלד ע”ב

Jacob is the secret of the upper world and his unity is one, and his sons are the secret of the lower world and their unity is one. Torah study grants merit in this world and in the world to come, and even the lips of the deceased murmur Torah words in the grave. Vayikhu li terumah means that Knesset Israel is taken from the supernal place of love. The terumah is given with the husband permission through prayer to cleave to the Holy One Blessed Be He.
