'One' in the Bible

So her sons married Moabite women. (One was named Orpah and the other Ruth.) And they continued to live there about ten years.

But she replied to them, "Don't call me 'Naomi'! Call me 'Mara' because the Sovereign One has treated me very harshly.

I left here full, but the Lord has caused me to return empty-handed. Why do you call me 'Naomi,' seeing that the Lord has opposed me, and the Sovereign One has caused me to suffer?"

One day Ruth the Moabite said to Naomi, "Let me go to the fields so I can gather grain behind whoever permits me to do so." Naomi replied, "You may go, my daughter."

She said, "You really are being kind to me, sir, for you have reassured and encouraged me, your servant, even though I am not one of your servants!"

Her mother-in-law asked her, "Where did you gather grain today? Where did you work? May the one who took notice of you be rewarded!" So Ruth told her mother-in-law with whom she had worked. She said, "The name of the man with whom I worked today is Boaz."

He said, "May you be rewarded by the Lord, my dear! This act of devotion is greater than what you did before. For you have not sought to marry one of the young men, whether rich or poor.

So she slept beside him until morning. She woke up while it was still dark. Boaz thought, "No one must know that a woman visited the threshing floor."
