from an interview (his last?)
PKD Fan Group regular Aharon Varady comments:
PKD was using the Hertz Ḥumash. Rabbi Hertz was the former Chief rabbi of Britain and his Ḥumash (the five books: Genesis, Exodus...) was pretty much the standard Hebrew-English volume available in synagogues when I was growing up. It's an interesting edition -- it's probably the first Jewish Hebrew-English ḥumash to include the commentary and scholarship of non-Jews that Rabbi Hertz considered valuable for his modern audience.
Oh and the verse in Deuteronomy is 24:15.
