'One' in the Bible

They took wives from the Moabite women; the name of the one was Orpah, and the name of the other was Ruth. They lived there about ten years;

Then Boaz said to Ruth, “Listen carefully, my daughter. Do not go to glean in another field or leave this one, but stay here close by my maids.

Then she said, “Let me find favor in your sight, my lord, for you have comforted me and have spoken kindly to your maidservant, though I am not as one of your maidservants.”

Naomi said to her daughter-in-law, “May he be blessed of the Lord who has not ceased His kindness to the living and to the dead.” Again Naomi said to her, “The man is one of our closest relatives, one who has the right to redeem us.”

So she lay at his feet until the morning, but got up before anyone could recognize another; Boaz said, “Do not let it be known that the woman came to the threshing floor [last night].”

So I thought to let you hear of it, saying, ‘Buy it in the presence of those sitting here, and before the elders of my people. If you will redeem it, redeem it; but if not, then tell me, so that I may know; for there is no one besides you to redeem it, and I am [next of kin] after you.’” And he said, “I will redeem it.”
