I'm sorry, but Bobbie Gentry did not write a song called "Away in a Manger." However, "Away in a Manger" is a well-known traditional Christmas carol, and there are various adaptations and versions of this song. The lyrics you provided are from one of the popular versions of the traditional carol. The song tells the story of the birth of Jesus Christ, as described in the biblical nativity story. It portrays the humble circumstances of Jesus' birth, with no crib for his bed, and how he lays down in a manger (a feeding trough for animals) with the stars shining down upon him. The lyrics mention how the cattle are lowing (making sounds), and though the baby wakes up, he doesn't cry. The singer expresses their love for Jesus and asks him to look down from the sky and stay by their side until morning comes. They ask Jesus to be near and love them, wishing for his everlasting presence. The song concludes with a blessing, asking Jesus to take care of all the dear children and bring them to heaven to live with him. Overall, "Away in a Manger" is a classic Christmas carol that celebrates the birth of Jesus and conveys a sense of love, innocence, and hope for blessings and eternal life.
