Numbers 21:8

And the Lord said unto Moses,.... Out of the cloud; or, it may be, Moses went into the sanctuary, and there prayed, and the Lord answered him from between the cherubim:

make them a fiery serpent; not a real one, but the likeness of one, one that should very much resemble the fiery serpents Israel had been bitten with:

and set it upon a pole; a standard, banner, or ensign, as the word signifies; perhaps meaning one of the poles on which their ensigns were carried: the Targum of Jonathan renders it, on an high place, that so it might be seen by all in the camp:

and it shall come to pass, that everyone that is bitten, when he looketh upon it, shall live; which is very wonderful, that by looking to the figure of a serpent, men should be cured of the bites of real ones, and which bites were deadly; the virtue of healing could not come from the figure, but from God, who appointed it to be made, the Targum of Jonathan adds, that one bitten should live,

"if he directed his heart to the Word of the Lord,''

even to that divine Logos or Word of God, whose lifting up was figured hereby; see John 3:14.
