Psalms 87:4

I will make mention of Rahab and Babylon to them that know Me, literally, "I will call to remembrance Rahab," that is, Egypt, "and Babylon as those who know Me," publishing the fact that people even from these heathen nations came to the knowledge of the truth. Behold Philistia, the heathen country southwest of Canaan, and Tyre, that is, Phenicia, with Ethiopia, the country south of Egypt; this man was born there, that is, people from all these nations, from belligerent Philistia, from commercial Phenicia, from powerful Ethiopia, would be gained for Jehovah; always there would be some out of the heathen nations who would accept Jehovah as their Savior.
