I am looking for a sefer which delineates the significance and meaning of many names in Torah, but more specifically the lists of names, found in Noach, Vayeira, Chayei Sarah, Vayishlach, Vayigash, etc.
For example, the Torah tells us the names of Yishmael's twelve sons. What is the significance of the Torah telling us his sons? Why bother?
Another example: the Torah tells us the names of Yokshan's and Midian's sons. What is the significance and why bother?
