'Mother's' in the Bible

So the girl went running and took the news of these things to her mother's house

And Isaac took Rebekah into his tent and she became his wife; and in his love for her, Isaac was comforted after his mother's death.

Let peoples be your servants, and nations go down before you: be lord over your brothers, and let your mother's sons go down before you: a curse be on everyone by whom you are cursed, and a blessing on those who give you a blessing.

But go to Paddan-aram, to the house of Bethuel, your mother's father, and there get yourself a wife from the daughters of Laban, your mother's brother.

Then when Jacob saw Rachel, the daughter of Laban, his mother's brother, coming with Laban's sheep, he came near, and rolling the stone away from the mouth of the hole, he got water for Laban's flock.

Then, lifting up his eyes, he saw Benjamin, his brother, his mother's son, and he said, Is this your youngest brother of whom you gave me word? And he said, God be good to you, my son.
