# seed
The word "seed" refers to what a man puts into a woman to cause a baby to grow inside the woman. Like the word "offspring," it can refer to more than one person. Try to find a word that is singular but can refer to more than one person.
The words "he" and "his" refer to the woman's descendant. If "seed" was translated as plural, this can be translated as "they will bruise ... their heel"; in this case, consider inserting footnotes to say that the "they" and "their" are used to translate a singular pronoun.
