Zohar on Tehillim 31 – A Spirit as a Pledge
Tehillim 31:6
- "B'yadkha afkid ruchi, padita oti Hashem El emet" - (into Your hands I entrust my spirit as a pledge).
Just as Noah chose the dove as his messenger, so too a person's soul (neshamah) chooses the spirit (ruach) as its messenger; therefore, a person is obligated to entrust his spirit as a pledge. Even a Jew who, because of the body's sins, is held captive by the forces of the yetzer hara is nevertheless redeemed by the Kadosh Baruch Hu.
(Zohar on Pinchas, Sulam, Zvi Nisanzen)
