יהושע ז:ט פירוש: רש״י

And what will you do for Your Name, which is associated with our name?²God’s Name, אֵל is part of our name יִשְׂרָאֵל. This is the Aggadic interpretation. The simple meaning is, What will you do for your mighty Name, that has already achieved such fame; and now they will be able to say, His strength has become lessened.
