that are written

This can be stated in active form. AT: "that I have written" (See: rc://en/ta/man/translate/figs-activepassive)

Here "heart" and "soul" are metonyms for a person's inner being. These two phrases are used together to mean "completely" or "earnestly." See how you translated this in Deuteronomy 4:29. (See: rc://en/ta/man/translate/figs-metonymy and rc://en/ta/man/translate/figs-doublet)
