Kommentar zu Divrej Hajamim I 13:10

and He struck him down because he stretched forth his hand upon the Ark This is what is written in II Samuel (6:7): “... and God struck him down there” עַל הַשַּׁל meaning עַל הַשֶּׁלַח, because he stretched forth to hold the Ark. Another example of this is (I Kings 21:23): “The dogs will devour Jezebel” בְּחֵל יִזְרְעֶאל. In another verse it is written: (II Kings 9:10): “בְּחֵלֶק יִזְרְעֶאל,” in the territory of Jezreel. So will we explain עַל הַשַּׁל here as הַשֶּׁלַח

and he died there before God before the Ark of God, and in (II Samuel 6:7): “...and there he died by the Ark of God.”
