Exodus 2:5

Exo. 2:5. Pharaoh's daughter became the mother of Moses, which typified the calling of the Gentile church, that is naturally the daughter of Satan, the spiritual Pharaoh, which becomes the church of Christ, and so his mother; and also is to represent that all the saints of which the whole church consists, are naturally the children of the devil, that by conversion become the spiritual mother of Christ, as Christ says that whosoever shall do the will of his Father which is in heaven, the same is his mother, etc. The whole church, which is often represented as the mother of Christ, is in her constituent parts naturally an Egyptian, and the daughter of Pharaoh. She found Moses when she came down to wash herself in the river. The river here represents the Holy Ghost, and the washing is the washing of regeneration, by which souls are brought to Christ, which is signified by baptism, by which their admission into the Christian church is declared and sealed. Pharaoh's daughter is more than once made use of in Scripture, to signify the church, especially the Gentile. So was Pharaoh's daughter that became Solomon's wife, for the church is figuratively both the wife and mother of Christ.

Exo. 2:5. Pharaoh's daughter came to Moses herself, into the same river into which Moses was cast. So, if we would find Christ, and be the spiritual mother of Christ, we must die with Christ, be made conformable to his death, be buried with him by baptism; must die to sin; must be crucified to the world, and die to the law, and be willing to suffer affliction and persecution with him. By such mortification and humiliation is the soul washed in the river into which Christ was cast.
