ra.hav is a proper name used for an adversary subdued by God in Job and for Egypt in Isaiah.

The name appears chiefly in Job within scenes of God’s anger, power, and the submission or defeat of Rahab; Isaiah 30:7 applies it to Egypt in a pronouncement about Egypt’s ineffective help.

1. Figure subdued beneath God · dominant

   In Job 26:12, the proper noun is the object of the action in the clause that the APB renders, “by his understanding he smites Rahab.” In Job 9:13, the APB places “the helpers of Rahab” beneath God as they “bow down,” within a statement that God does not turn back his anger.

2. Name applied to Egypt · occasional

   In Isaiah 30:7, the proper noun occurs after the statement about Egypt’s vain and empty help; the APB renders the conclusion, “therefore I have called her Rahab who sits still.”

   Isaiah 30:7

In the Anselm Project Bible: The APB retains “Rahab” in all three verses. In Isaiah 30:7 it explicitly says that Egypt is called Rahab, while the Job verses present Rahab as smitten or having helpers who bow down.
