Numbers 21:5-7

Young's Literal Translation

⁵ and the people speak against God, and against Moses, `Why hast thou brought us up out of Egypt to die in a wilderness? for there is no bread, and there is no water, and our soul hath been weary of this light bread.'

⁶ And Jehovah sendeth among the people the burning serpents, and they bite the people, and much people of Israel die;

⁷ and the people come in unto Moses and say, `We have sinned, for we have spoken against Jehovah, and against thee; pray unto Jehovah, and He doth turn aside from us the serpent;' and Moses prayeth in behalf of the people.
