* In the New Testament, the term "flesh" is used to refer to the sinful nature of human beings. This is often used in contrast to their spiritual nature.
* The expression "own flesh and blood" refers to someone who is biologically related to another person, such as a parent, sibling, child, or grandchild.
* The expression "flesh and blood" could also be translated as "relatives" or "family" or "kinfolk" or "family clan." There may be contexts where it could be translated as "ancestors" or "descendants."
* The expression "become one flesh" could be translated as "unite sexually" or "become as one body" or "become like one person in body and spirit." The translation of this expression should be checked to make sure it is acceptable in the project language and culture. (See: [euphemism](rc://en/ta/man/translate/figs-euphemism)). It should also be understood that this is figurative, and does not mean that a man and a woman who "become one flesh" literally become one person.
