פירוש על ברכות 36:13

A word meaning "silence" used in the Psalms to describe the silence of the grave ; cf. Ps. xciv. 17, cxv. 17. In the Talmud it is the name of the guardian angel of the departed.

He announces to the disembodied spirits who will soon join them ; but otherwise the dead do not know what transpires on earth.
