Genesis 24:2

tn The Hebrew term זָקֵן (zaqen) may refer to the servant who is oldest in age or senior in authority (or both).

sn Put your hand under my thigh. The taking of this oath had to do with the sanctity of the family and the continuation of the family line. See D. R. Freedman, “Put Your Hand Under My Thigh—the Patriarchal Oath,” BAR 2 (1976): 2–4, 42.
