Origen

(tom. vi. c. 24) Bethabara means house of preparation; which agreeth with the baptism of Him, who was making ready a people prepared for the Lord. (c.25. et seq.). Jordan, again, means, “their descent.” Now what is this river but our Saviour, through Whom coming into this earth all must be cleansed, in that He came down not for His own sake, but for theirs. This river it is which separateth the lots given by Moses, from those given by Jesus; its streams make glad the city of God. (c. 29). As the serpent lies hid in the Egyptian river, so doth God in this; for the Father is in the Son. Wherefore whosoever go thither to wash themselves, lay aside the reproach of Egypt, (Joshua 5:9.) are made meet to receive the inheritance, are cleansed from leprosy, (2 Kings 5:14.) are made capable of a double portion of grace, and ready to receive the Holy Spirit; (2 Kings 2:9.) nor doth the spiritual dove light upon any other river. John again baptizes beyond Jordan, as the precursor of Him Who came not to call the righteous, but sinners to repentance.
