Exodus 15:25

Cast - Worn-out; old; cast-off.

He cried unto the Lord - Moses was not only their leader, but also their mediator. Of prayer and dependence on the Almighty, the great mass of the Israelites appear to have had little knowledge at this time. Moses, therefore, had much to bear from their weakness, and the merciful Lord was long-suffering.

The Lord showed him a tree - What this tree was we know not: some think that the tree was extremely bitter itself, such as the quassia; and that God acted in this as he generally does, correcting contraries by contraries, which, among the ancient physicians, was a favourite maxim, Clavus clavo expellitur. The Targums of Jonathan and Jerusalem say that, when Moses prayed, "the Word of the Lord showed him the tree ארדפני ardiphney, on which he wrote the great and precious name of (Jehovah), and then threw it into the waters, and the waters thereby became sweet" But what the tree ardiphney was we are not informed.

Many suppose that this tree which healed the bitter waters was symbolical of the cross of our blessed Redeemer, that has been the means of healing infected nature, and through the virtue of which the evils and bitters of life are sweetened, and rendered subservient to the best interests of God's followers. Whatever may be in the metaphor, this is true in fact; and hence the greatest of apostles gloried in the cross of our Lord Jesus Christ, by which the world was crucified to him and he unto the world.

It appears that these waters were sweetened only for that occasion, as Dr. Shaw reports them to be still brackish, which appears to be occasioned by the abundance of natron which prevails in the surrounding soil. Thus we may infer that the natural cause of their bitterness or brackishness was permitted to resume its operations, when the occasion that rendered the change necessary had ceased to exist. Thus Christ simply changed that water into wine which was to be drawn out to be carried to the master of the feast; the rest of the water in the pots remaining as before. As the water of the Nile was so peculiarly excellent, to which they had been long accustomed, they could not easily put up with what was indifferent. See Clarke's note on Exodus 7:18.

There he made for them - Though it is probable that the Israelites are here intended, yet the word לו lo should not be translated for them, but to him, for these statutes were given to Moses that he might deliver them to the people.

There he proved them - נסהו nissahu, he proved Him. By this murmuring of the people he proved Moses, to see, speaking after the manner of men, whether he would be faithful, and, in the midst of the trials to which he was likely to be exposed, whether he would continue to trust in the Lord, and seek all his help from him.

A tree ... - The statement points to a natural agency, but the result was manifestly supernatural.

He made ... - The Lord then set before them the fundamental principle of implicit trust, to be shown by obedience. The healing of the water was a symbol of deliverance from physical and spiritual evils.

15:25 And he cried unto the Lord - It is the greatest relief of the cares of magistrates and ministers, when those under their charge make them uneasy, that they may have recourse to God by prayer; he is the guide of the church's guides, and to the chief shepherd, the under shepherds must on all occasions apply themselves: And the Lord directed Moses to a tree, which he cast into the waters, and they were made sweet - Some think this wood had a peculiar virtue in it for this purpose, because it is said, God shewed him the tree. God is to be acknowledged, not only in the creating things useful for man, but in discovering their usefulness. But perhaps this was only a sign, and not a means of the cure, no more than the brazen serpent. There he made a statute and an ordinance, and there he proved them - That is, there he put them upon trial, admitted them as probationers for his favour. In short he tells them, 15:26 , what he expected from them, and that was, in one word,obedience. They must diligently hearken to his voice, and give ear to his commandments, and must take care, in every thing, to do that which was right in God's sight, and to keep all his statutes. Then I will put none of these diseases upon thee - That is, I will not bring upon thee any of the plagues of Egypt. This intimates, that if they were disobedient, the plagues which they had seen inflicted on their enemies should be brought on them. But if thou wilt be obedient, thou shalt be safe, the threatening is implied, but the promise is expressed, I am the Lord that healeth thee - And will take care of thee wherever thou goest.
