Halakhah su Isaia 65:23

On a fast day, an individual recites the sixteenth blessing according to this formula. Hear our voice, Lord our God, have pity and mercy on us and receive in mercy and in favor our prayers before you. Do not cause us to return empty-handed, our King. Answer us, our Father, answer us on our fast day because in this great distress we do not turn your face from us and do not block your ears from hearing our pleas and may our salvation be soon. Before we call, you answer, we speak and you listen as it is said, "And it will be that before they call, I will answer (Isaiah 65:23)." They also say, "And I will hear because you hear the prayer of of every mouth." Blessed are You, Adonai, who hears prayer. And the representative of the community recites this blessing on behalf of himself. After the seventh blessing, he says "Answer us, etc." until "because you answer at a time of trouble, redeem and rescue us at every time of trouble and distress. Blessed are You, Lord who answers at times of trouble."
