At least three times.
Joshua 3:15-17
2 Kings 2:8, by Elijah
2 Kings 2:14, by Elisha
Okay, I'm parking here for a little while and meditating on these scriptures! There's something here for us! I'm digging! I'm sensing secret manna!! LOL!
Jordan = judgment
River/Water = Holy Spirit
Elijah = God the Lord, the strong Lord
Elisha = salvation of God
Joshua = Savior, Deliverer
When the Jordan River overflows it's banks at times, it could symbolize judgment being poured out on the land - or lots of judgment in the land - more than usual.
Still "chewing the cud" on this one! Feel free to jump in if you have any insight from the Lord!
