'Sons' in the Bible

And it came to pass in the days when the judges judged, that there was a famine in the land. And a certain man of Bethlehem-judah went 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, Turn again, my daughters: why will ye go with me? have I yet sons in my womb, that they may be your husbands?

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

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