Numbers 21:7

4 And they journey from mount Hor, the way of the Red Sea, to compass the land of Edom, and the soul of the people is short in the way,

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.

8 And Jehovah saith unto Moses, `Make for thee a burning [serpent], and set it on an ensign; and it hath been, every one who is bitten and hath seen it -- he hath lived.

9 And Moses maketh a serpent of brass, and setteth it on the ensign, and it hath been, if the serpent hath bitten any man, and he hath looked expectingly unto the serpent of brass -- he hath lived.

10 And the sons of Israel journey, and encamp in Oboth.
