with all your heart, with all your soul, and with all your might

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