Sirach 48:19-25

19 Then trembled their hearts and hands, and they were in pain, as women in travail.
20 But they called upon the Lord which is merciful, and stretched out their hands toward him: and immediately the Holy One heard them out of heaven, and delivered them by the ministry of Esay.
21 He smote the host of the Assyrians, and his angel destroyed them.
22 For Ezekias had done the thing that pleased the Lord, and was strong in the ways of David his father, as Esay the prophet, who was great and faithful in his vision, had commanded him.
23 In his time the sun went backward, and he lengthened the king's life.
24 He saw by an excellent spirit what should come to pass at the last, and he comforted them that mourned in Sion.
25 He shewed what should come to pass for ever, and secret things or ever they came.
