I think that Professor Galil's interpretation is more convincing than the older ones. The text seems to be Hebrew. However, I don't agree with the view that the content was "unfamiliar to all the cultures in the region besides the Hebrew society". You can find the same ideal in the older Canaanite texts from Ugarit (Syrian coast), where the same terminology is used (KTU 1.16:vi.33.46-50 and 1.17:v.7-8).
