4:25,26 Our first parents were comforted in their affliction by the birth of a son, whom they called Seth, that is, 'set,' 'settled,' or 'placed;' in his seed mankind should continue to the end of time, and from him the Messiah should descend. While Cain, the head of the apostacy, is made a wanderer, Seth, from whom the true church was to come, is one fixed. In Christ and his church is the only true settlement. Seth walked in the steps of his martyred brother Abel; he was a partaker of like precious faith in the righteousness of our God and Saviour Jesus Christ, and so became a fresh witness of the grace and influence of God the Holy Spirit. God gave Adam and Eve to see the revival of religion in their family. The worshippers of God began to do more in religion; some, by an open profession of true religion, protested against the wickedness of the world around. The worse others are, the better we should be, and the more zealous. Then began the distinction between professors and profane, which has been kept up ever since, and will be, while the world stands.

23, 24. Lamech said unto his wives—This speech is in a poetical form, probably the fragment of an old poem, transmitted to the time of Moses. It seems to indicate that Lamech had slain a man in self-defense, and its drift is to assure his wives, by the preservation of Cain, that an unintentional homicide, as he was, could be in no danger.
