'Sons' in the Bible

And it came to pass in the days when the judges ruled, that there was a famine in the land. And a certain man went from Bethlehem-Judah, to sojourn in the country of Moab, he, and his wife, and his two sons.

And the name of the man was Elimelech, and the name of his wife Naomi, and the name of his two sons Mahlon and Chilion, Ephrathites of Bethlehem-Judah. And they came into the country of Moab, and continued there.

And Elimelech Naomi's husband died; and she was left, and her two sons.

And Naomi said, Return, my daughters: why will ye go with me? Are there yet sons in my womb, that they could be your husbands?

Return, my daughters, go; for I am too old to have a husband. If I should say, I have hope, should I even have a husband to-night, and should I also bear sons,

And he shall be to thee a restorer of thy life, and a nourisher of thine old age; for thy daughter-in-law who loves thee, who is better to thee than seven sons, has borne him.
