It is sometimes claimed that the prophet Yirmyahu cites P. For instance, Yirmyahu 3:16 reads:
And it shall be when you multiply and become fruitful in the land, in those days - the words of Hashem - they will no longer say, 'The Ark of the Covenant of Hashem,' and it will not come to mind; they will not mention it and will not recall it, and it will not be used any more.
Here is, however, a citation, not of P proper, but of H, from Vayikra 26:9. Another would-be citation of P is Yirmyahu 7:22:
For I did not speak with your forefathers, nor did I command them, on the day I took them out of Mitzrayim, concerning burnt- or peace offering.
But this Pasuk may be read as a contradiction of H, namely from its very beginning to its very end, Vayikra 17:8 and Vayikra 26:46. Another would-be citation of P is Yirmyahu 4:23:
I saw the land, and behold, it was void and empty; to the heavens and their light was gone.
But this Pasuk contains, in our view, a citation of E.
From our perspective, Yirmyahu could not cite P proper because P did not exist in the days of Yirmyahu. H did exist, and was in fact an extremely crucial impetus for the construction of D.
