The angel Lailah or Laylah (Heb. לַיְלָה") is an angel in some interpretations in the Talmud and in some later Jewish mythology.
Lailah is the Hebrew word for "night" laylah לילה, aswell as the angel of childbirth and pregnency.
TheMidrash Tanhuma explains how Lailah is in charge of conception (לַמַּלְאָךְ הַמְּמֻנָּה עַל הַהֵרָיוֹן) and tells the story of how he is instructed to move souls from the Garden of Eden to a mothers womb.
Lailah is the only angel recorded with a feminine name and specifically feminine characteristics. She is considered the opposite angel of the demon Lilith, Lilith is said to kill and eat children while lailah is said to protect them, it is also said that she helped Abraham when it mentions the night working with him,
