Jasher 37:14-19
14 Jacob prayed to the Lord for his sons, and he spread forth his hands to the Lord, and said, O God, you are an Almighty God, you are our father; you did form us and we are the works of your hands; I pray you deliver my sons through your mercy from the hand of their enemies who are this day coming to fight with them and save them from their hand, for in your hand is power and might to save the few from the many. 15 And give to my sons, your servants, strength of heart and might to fight with their enemies, to subdue them, and to make their enemies fall before them. Let not my sons and their servants die through the hands of the children of Canaan. 16 But if it seems good in your eyes to take away the lives of my sons and their servants, take them in your great mercy through the hands of your ministers, that they may not perish this day by the hands of the kings of the Amorites. 17 When Jacob ceased praying to the Lord the earth shook from its place, and the sun darkened, and all these kings were terrified and a great consternation seized them. 18 The Lord listened to the prayer of Jacob, and the Lord impressed the hearts of all the kings and their hosts with the terror and awe of the sons of Jacob. 19 For the Lord caused them to hear the voice of chariots, and the voice of mighty horses from the sons of Jacob, and the voice of a great army accompanying them.
