John Calvin on Joshua 4:9

9. And Joshua set up twelve stones, etc Apparently there was no use of stones under the water, and it may therefore seem to have been absurd to bury stones at a depth. The others which were placed in Gilgal being publicly visible, furnished occasion for inquiry; but stones hidden from the eyes of men at the bottom of the water could have no effect in inciting their minds. I admit that a monument altogether buried in silence would have been useless. French, “Or je confesse bien que c’eust este un tesmoignage du tout inutile, si on l’eust laisse la comme enseveli sans en parler;” “Now, I confess, that it would have been an entirely useless testimony had they left it there, as it were, buried without speaking of it.” — Ed. But when they talked among themselves of the evidence of the passage left there, the hearing even of what they did not see, strongly tended to confirm their faith. The ark of the covenant was shut up in the sanctuary and covered by a veil placed over against it, and yet its hidden splendor was not without benefit, when they learned from the Law that the covenant of God was deposited in it. It might also happen, that when the river was low, the tops of the heap would sometimes appear. But what I have already said is more probable, that though Joshua buried the stones in the middle of the stream, he did a useful act by establishing a testimony in presence of the people, which would afterwards become the subject of general conversation.

Joshua 4:10-18

10. For the priests which bare the ark stood in the midst of Jordan, until every thing was finished that the LORD commanded Joshua to speak unto the people, according to all that Moses commanded Joshua: and the people hasted and passed over.

10. Sacerdotes autem portantes arcam stabant in medio Jordanis donec compleretur omnis sermo quem praeceperat Jehova ad Josuam, ut diceret populo: prorsus ut praeceperat Moses ipsi Josue: festinavit autem populus transeundo.

11. And it came to pass, when all the people were clean passed over, that the ark of the LORD passed over, and the priests, in the presence of the people.

11. Quum vero transeundi finem fecisset universus populus, transivit arca Jehovae, et sacerdotes coram populo.

12. And the children of Reuben, and the children of Gad, and half the tribe of Manasseh, passed over armed before the children of Israel, as Moses spoke unto them:

12. Transierunt quoque filii Reuben, et filii Gad, et dimidia tribus Manasse armati ante filios Israel: quemadmodum loquutus fuerat ad eos Moses.

13. About forty thousand prepared for war passed over before the LORD unto battle, to the plains of Jericho.

13. Quadraginta millia armatorum transierunt coram Jehova ad praelium ad campestria Jericho.

14. On that day the LORD magnified Joshua in the sight of all Israel; and they feared him, as they feared Moses, all the days of his life.

14. Eo die magnificavit Jehova Josuam in oculis totius Israelis: et timuerunt eum quemad modum timuerant Mosen omnibus diebus vitae ejus.

15. And the LORD spoke unto Joshua, saying,

15. Loquutus est autem Jehova ad Josuam, dicendo,

16. Command the priests that bear the ark of the testimony, that they come up out of Jordan.

16. Praecipe sacerdotibus portantibus arcam testimonii ut ascendant e Jordane.

17. Joshua therefore commanded the priests, saying, Come you up out of Jordan.

17. Et praecepit Josue sacerdotibus, dicendo, Ascendite ex Jordane.

18. And it came to pass, when the priests that bare the ark of the covenant of the LORD were come up out of the midst of Jordan, and the soles of the priests’ feet were lifted up unto the dry land, that the waters of Jordan returned unto their place, and flowed over all his banks, as they did before.

18. Porro quum ascendissent sacerdotes portantes arcam foederis Jehovae e medio Jordane, et translatae essent plantae pedum sacerdotum in siccum, reversae sunt aquae Jordanis ad locum suum, et fluxerunt sicut heri et nudius tertius, super omnes ripas ejus.
