(8) Make thee a fiery serpent.--The single Hebrew word which is here employed is saraph (a seraph), or burning one, as in Numbers 21:6, where the word nehashim--serpents--occurs also. The meaning is explained in the following verse, in which it is said that Moses made "a serpent of brass."

Set it upon a pole.--Better, a standard. The LXX. have ???????, the Vulgate signum. The Hebrew word (nes) is the same which occurs in Exodus 17:15, "Jehovah-nissi"--i.e., Jehovah is my standard or banner.

Verse 8. - Make thee a fiery serpent. A saraph. The Septuagint, not understanding the meaning of saraph, has simply ὄφιν (cf. John 3:14). Set it upon a pole. גֵם Septuagint σήμειον. Vulgate, signum. The same word is better translated "ensign" in such passages as Isaiah 11:10; "banner" in such as Psalm 60:4; "standard" in such as Jeremiah 51:27. The "pole" may have been the tallest and most conspicuous of those military standards which were planted (probably on some elevation) as rallying points for the various camps; or it may have been one loftier still, made for the occasion.

21:4-9 The children of Israel were wearied by a long march round the land of Edom. They speak discontentedly of what God had done for them, and distrustfully of what he would do. What will they be pleased with, whom manna will not please? Let not the contempt which some cast on the word of God, make us value it less. It is the bread of life, substantial bread, and will nourish those who by faith feed upon it, to eternal life, whoever may call it light bread. We see the righteous judgment God brought upon them for murmuring. He sent fiery serpents among them, which bit or stung many to death. It is to be feared that they would not have owned the sin, if they had not felt the smart; but they relent under the rod. And God made a wonderful provision for their relief. The Jews themselves say it was not the sight of the brazen serpent that cured; but in looking up to it, they looked up to God as the Lord that healed them. There was much gospel in this. Our Saviour declared, Joh 3:14,15, that as Moses lifted up the serpent in the wilderness, so the Son of man must be lifted up, that whatsoever believeth in him, should not perish. Compare their disease and ours. Sin bites like a serpent, and stings like an adder. Compare the application of their remedy and ours. They looked and lived, and we, if we believe, shall not perish. It is by faith that we look unto Jesus, Heb 12:2. Whosoever looked, however desperate his case, or feeble his sight, or distant his place, was certainly and perfectly cured. The Lord can relieve us from dangers and distresses, by means which human reason never would have devised. Oh that the venom of the old serpent, inflaming men's passions, and causing them to commit sins which end in their eternal destruction, were as sensibly felt, and the danger as plainly seen, as the Israelites felt pain from the bite of the fiery serpents, and feared the death which followed! Then none would shut their eyes to Christ, or turn from his gospel. Then a crucified Saviour would be so valued, that all things else would be accounted loss for him; then, without delay, and with earnestness and simplicity, all would apply to him in the appointed way, crying, Lord, save us; we perish! Nor would any abuse the freeness of Christ's salvation, while they reckoned the price which it cost him.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.
