Exodus 15:25

He cried unto the Lord Moses did what they ought to have done. He made request unto the Lord for help in this distress. 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. The Lord showed him a tree What tree this was is quite uncertain. And although some have been of opinion that it had a peculiar virtue in it to render the bitter waters sweet, because it is said, God showed him the tree, yet since they were made sweet immediately upon casting the tree into them, and that to such a degree as to correct the taste of them for many hundreds of thousands of people, not to mention the numerous flocks and herds, it seems perfectly evident that this effect must have been miraculous, and that the tree was only a sign, and not the means of the cure, any more than the brazen serpent in another case. May not this tree be considered as an emblem of the cross of Christ, and of the blessings purchased thereby, which, when we receive them in faith, sweeten our bitterest trials with the peace and love of God, peace of conscience, and lively, joyful hopes of everlasting blessedness? There he made them a statute and an ordinance God, having now eased them of the hard and iron yoke of the Egyptians, puts his sweet and easy yoke upon them, and having undertaken to be their king, protector, and leader, he claims their subjection to himself, and to his laws and statutes. It seems, however, that all he now did was to give them some general intimations of his will, previous to the promulgation of his law. According to the tradition of the Jews, the statute and ordinance now given was, that they should observe the sabbath, and do justice. There he proved or tried them That is, he both tried their faith by the difficulty now mentioned, namely, their want of water, and their future obedience by this general command, afterward branched out into divers particulars.
