“Before he had finished speaking, behold, Rebekah who was born to Bethuel the son of Milcah, the wife of Abraham’s brother Nahor, came out with her jar on her shoulder. The girl was very beautiful, a virgin, and no man had had relations with her; and she went down to the spring and filled her jar and came up. – Gen. 24:15-16
Abraham’s servants’ prayer in the previous verse is considered one of the greatest and most effective prayers in history, as the answer to it started to come about before the servant was even finished speaking (v. 15). As many scholars have noted, the timing of the prayer and its subsequent answer infer that God had already set everything in motion previously (the servant had a long journey, for instance).
Rebekah’s father is Bethuel. Bethuel is the son of Nahor and Milcah. Nahor, in turn, is the son of Terah, who is also Abraham’s father (Gen. 11:27). Therefore Abraham is related to Rebekah, though not extremely closely.
The etymology of Rebekah’s name, according to the BDB Theological Dictionary means “to tie firmly”. Other sources define the meaning as ‘a knotted cord’. As I believe Rebekah is a picture of the church, what comes to mind is Ecclesiasties 4:12(b): “A cord of three strands is not quickly torn apart” which many believe is a reference to the doctrine of the Trinity.
