'One' in the Bible

And {they took} for themselves Moabite wives. The name of the one [was] Orpah and the name of the other [was] Ruth. And they lived there about ten years.

And Boaz said to Ruth, "{Listen carefully}, my daughter, go no longer to glean in another field. Moreover, do not leave from this one, but {stay close} with my young women.

And she said, "May I find favor in your eyes, my lord, for you have comforted me and have spoken {kindly to your servant}, and I am not one of your servants."

And Naomi said to her daughter-in-law, "[May] he be blessed by Yahweh, whose loyal love has not forsaken the living or the dead." And Naomi said to her, "The man is a close relative for us, he [is] one of our redeemers."

And I thought {I would tell you} and say, '{Buy it in the presence of} those sitting and before the elders of my people,' if you want to redeem [it], redeem [it]. But if you do not want to redeem, tell me so that I may know, for there is no one except you to redeem [it], and I [am] after you." And he said, "I want to redeem [it]."
