According to the Haggada (book 1, chapter 4: Punishment of the Fallen Angels), the angel Shemhazai lusted after a maiden named Istehar, however, she tricked him to reveal the Ineffable Name of God. Istehar used the name to ascend to heaven and escaped her violation by Shemhazai. God rewarded Istehar for her by commemorating her as the seven-star constellation Pleides.
