תּלמוד אויף הושע 14:5

But God, if a man commits a transgression in secret, is appeased by him merely with words. As it is said: "Take with you words, and return to the Lord." (Hosea 14:3) And not only that, God considers it a good deed! As it is said: "Accept that which is good." (ibid.) And not only that, Scripture exalts him as if he had sacrificed bulls. As it is said: "We will offer the bulls of our lips." (ibid.) In case you say that bulls are obligatory, Scripture says: "I will heal their backsliding, I will love them freely." (Hosea 14:5)
