Chapter 1 of Joshua concerns the taking of the land, which typifies the gaining of Christ, and ch. 2 concerns the gaining of the proper persons to bring forth Christ that Christ might be spread and increased (John 3:30). God provided Joshua for the gaining of the land, and He provided a Gentile female, Rahab the harlot, for the spreading of Christ. Rahab was a condemned Canaanite qualified to be destroyed, but she became one of the main ancestors of Christ. By turning to God and His people and by marrying Salmon (Matt. 1:5a), the son of a leader of Judah, a leading tribe of Israel (1 Chron. 2:10-11), and probably one of the two spies, she became associated with Christ in His incarnation for the fulfillment of God’s eternal economy. This is a strong sign that the history recorded in Joshua is in line with God’s eternal economy concerning Christ. See note Matt. 1:51a.
