Les Psaumes 149:5 Cabale : Sha'arei Kedusha

Reciting the Shema upon retiring to sleep: Know what our sages, of blessed memory, stated,⁷²⁵Zohar III 212a-b “One who recites the Shema upon his bed kills myriads of destructive forces found at night, particularly when his soul ascends above. This is as stated,⁷²⁶Psalms 149:5-6 ‘Let the pious (Chassidim) exalt in glory, let them sing joyously upon their beds. The praises of exaltation of God are in their throats, and a double-edged sword is in their hand.’”
