This personal name belongs to one of Nahor's eight sons by his wife Milcah, making him Abraham's nephew. The name's etymology is uncertain, though some suggest a connection to weeping or dripping. Like several of Nahor's sons, Jidlaph represents an Aramean tribal ancestor, though no further biblical narrative develops his lineage. His inclusion in the genealogy establishes the broader kinship network connecting Abraham to Mesopotamian peoples.
