I will sprinkle pure water on you so you will be clean; you will be purified from all of your uncleanness, and I will purify you from all of your idols

Yahweh forgiving the people and causing them to no longer sin is spoken of as if he would cleanse them with water. The phrase "you will be purified" can be stated in active form. Alternate translation: "I will forgive you and cause you not to sin as if I were sprinkling pure water on you so you will be clean; I will purify you from all of your uncleanness, and I will purify you from all of your idols" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-activepassive)

all of your uncleanness
