'Prayers' in the Bible

And Samuel took a young lamb, offering all of it as a burned offering to the Lord; and Samuel made prayers to the Lord for Israel and the Lord gave him an answer.

When Jacob and his sons had come into Egypt, and were crushed by the Egyptians, the prayers of your fathers came up to the Lord, and the Lord sent Moses and Aaron, who took your fathers out of Egypt, and he put them into this place.

And as for me, never will I go against the orders of the Lord by giving up my prayers for you: but I will go on teaching you the good and right way.
