because he slew me not from the womb; and so my mother would have been my grave, and her womb always great.

Because he did not put me to death before my birth took place: so my mother's body would have been my last resting-place, and she would have been with child for ever.

Δια τι δεν εθανατωθην εκ μητρας; η η μητηρ μου δεν εγεινε ταφος εις εμε και η μητρα αυτης δεν με εβαστασεν εις αιωνιον συλληψιν;

Because he slew me not from the womb; or that my mother might have been my grave, and her womb to be always great with me.

because he didn’t kill me from the womb. So my mother would have been my grave, and her womb always great.
