Albert Barnes Commentary Joshua 3:17

"And the priests that bare the ark of the covenant of Jehovah stood firm on dry ground in the midst of the Jordan; and all Israel passed over on dry ground, until all the nation were passed clean over the Jordan." — Joshua 3:17 (ASV)

The miraculous passage to the Holy Land through the Jordan is no less rich in typological meaning than that through the Red Sea (Compare to 1 Corinthians 10:1–2).

The solemn inauguration of Joshua to his office and his miraculous attestation by the same waters with which Jesus was baptized when He entered upon the public exercise of His ministry ; the choice of twelve men, one from each tribe, to be the bearers of the twelve stones and the builders of the monument erected with them (Compare to 1 Corinthians 3:10; Revelation 21:14): these were divinely-ordered occurrences that had a significance extending beyond their immediate one for Israel.

Nor, from this perspective, must the name “Adam”—the place where the stream that cut them off from the promises flowed toward the people—and the temporary failure under Joshua's rule of the full and rapid flood that supplies the Dead Sea, be overlooked.
