Branch, the father of Nahor (Gen. 11:20-23); called Saruch in Luke 3:35.
Serug
Serug is a name in a family line, and the line itself is the point. Genesis 11 passes from Reu to Serug and on to Nahor, giving each man’s years in the same steady pattern: he lived so long, had a son, and “begat sons and daughters.” Nahor was Abraham’s grandfather, so Serug sits a few steps before the call of Abram. Luke 3:35 lists him again, spelled Saruch, in the ancestry of Jesus. He does nothing in the story, but the lists show how the promise was passed down patiently, one generation after another.
