Jeremiah 2:22

Though thou shouldest wash thyself with nitre, and multiply to thyself soap, [still] thou art stained by thine iniquities before me, saith the Lord.

Though you should wash yourself with nitre, and multiply to yourself soap, [still] you are stained by your iniquities before me, says the Lord.

For though you wash yourself with lye, and use much soap, yet your iniquity is marked before me,” says the Lord Yahweh.
