Commentaire sur Josué 4:11

And it was when all the people had finished crossing and the Ark crossed. The Ark did not cross as the others did, but in the manner explained below:³Verse 18. ‘The soles of the feet of the Kohanim were lifted and they were moved back to the dry land, on the bank from which they initially entered. They were standing next to it and the waters were returned to their course to flow as they did before. The result of all this was that the Ark and its bearers were on this side and all the Bnei Yisroel were on the other (lit. this) side. The Ark then lifted its bearers and crossed over.’

In the people’s presence. Before the eyes of the people.
