Setting aside the conspiracy theorist tone characteristic of apologists (e.g., 'They just don't want to accept divine inspiration and want to find ways to disprove it!') and the begged question of divine inspiration itself, the first thing I noticed is the problem of leaving terms undefined. Like 'dependence'. What is this supposed to mean? And how does it contrast with 'similarity'?
The author of that article is pretty foggy on this; scholars already attribute the parallels to
similar backgrounds and thus similar forms of expression between Israel and other ANE civilizations. In Psa xxix, for instance, that doesn't eliminate its uniqueness as its own literary piece, but at the same time it doesn't mean we don't have here an example of an understanding of Yahweh in a similar way the storm god Baal was understood; sort of a syncretism or assimilation from the contact of Baal and Yahwistic cult. The article dismisses this by treating the Hebrew bible as a
monolithic work, making generalizations about what's in reality a diversity of material and confusing all sorts of chronologically and ideologically separate passages in the Hebrew bible. The methodology is just poor. And the quotes are misleading, but apologists stack them because the unwary reader wouldn't know otherwise. Apologists don't write for the scholar community, they write for church-goers. It's really ridiculous and lacks sophistication.
And yes, some of the prophets preached a universally significant message, but that has nothing to do with the prophets or anything else in the Hebrew bible being written 'for gentiles'. That assertion is obviously inspired by the Christian conviction that there's a god (namely, Yahweh) who himself inspired the bible for the world to read...and that's just not scholarship.
In the case of the poetical erotica (which is what the Song of Songs is: a poem about sex cast in metaphor) and wisdom literature of Egypt, this was shared by several ANE cultures. There are cases of
direct literary dependence though, like the Proverbs on the much older teachings of Amenemope. The Solomon-Egypt connection, btw, seems to me to be superficial and weak. None of the biblical wisdom literature we possess dates from that time.
You can tell I just don't like apologists.
