When there were no depths, I was brought forth; when there were no fountains abounding with water. When there were no depths - תהמות tehomoth, before the original chaotic mass was formed. See Genesis 1:2.
I was brought forth - חוללתי cholalti, "I was produced as by laboring throes." Mr. Parkhurst thinks that the heathen poets derived their idea of Minerva's (wisdom's) being born of Jupiter's brain, from some such high poetic personification as that in the text.
