'Young' in the Bible

And Boaz said to his servant {in charge of the reapers}, "To whom [does] this young woman [belong]?"

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 he said, "You [are] blessed by Yahweh my daughter. You did better [in this] last kindness than the first by not going after young men, whether poor or rich.

And may your house be like the house of Perez, whom Tamar bore to Judah from the offspring that Yahweh will give to you from this young woman."
