This is the name of one of Judah's sons. See how you translated this name in [Genesis 38:5](../38/05.md). (See: [[rc://en/ta/man/jit/translate-names]])
This is a polite way of saying that Judah did not have sexual relations with her again. You may need to use another euphemism in your language. (See: [[rc://en/ta/man/jit/figs-euphemism]])
