'Mother's' in the Bible

Besides, she really is my sister she's my father's daughter, but not my mother's daughter so she could become my wife.

The young woman then ran ahead and informed her mother's household what had happened.

May people serve and bow before you; may you be master over your brothers; may your mother's sons bow before you; may anyone who curses you be cursed; and may anyone who blesses you be blessed."

Instead, get up, travel to Paddan-aram, and visit the household of Bethuel, your mother's father. Marry one of Laban's daughters, since he's your mother's brother.

After Jacob had obeyed his father and mother's instructions to set out for Paddan-aram,

When Jacob saw Rachel, the daughter of Laban, his mother's brother, accompanied by Laban's sheep, Jacob approached the well, rolled the stone from the opening of the well, and then watered his mother's brother Laban's flock.

As Joseph looked up and recognized his brother Benjamin, his own mother's son, he asked, "Is this your youngest brother about whom you spoke to me?" And he addressed him directly, "May God be gracious to you, my son."
