'Child' in the Bible

Adam was intimate with his wife Eve, and she conceived and gave birth to Cain. She said, “I have had a male child with the Lord’s help.”

Adam was intimate with his wife again, and she gave birth to a son and named him Seth, for she said, “God has given me another child in place of Abel, since Cain killed him.”

Adam was 130 years old when he fathered a son in his likeness, according to his image, and named him Seth.

Sarai was unable to conceive; she did not have a child.

Abraham fell facedown. Then he laughed and said to himself, “Can a child be born to a hundred-year-old man? Can Sarah, a ninety-year-old woman, give birth?”

The child grew and was weaned, and Abraham held a great feast on the day Isaac was weaned.

and we answered my lord, ‘We have an elderly father and a younger brother, the child of his old age. The boy’s brother is dead. He is the only one of his mother’s sons left, and his father loves him.’
