כָּל־הָאֶזְרָ֥ח יַעֲשֶׂה־כָּ֖כָה אֶת־אֵ֑לֶּה לְהַקְרִ֛יב אִשֵּׁ֥ה רֵֽיחַ־נִיחֹ֖חַ לַֽיהוָֽה׃
Todo natural hará estas cosas así, para ofrecer ofrenda encendida de olor suave á SEÑOR.
Rabbeinu Bahya
זה אלי ואנוהו, “this is my G’d and I want to exalt Him.” According to the plain meaning of the text the meaning of ואנוהו is “I wish to build a residence for Him.” This is why Moses continues in verse 13 speaking about נוה קדשך, “Your holy abode.” The Holy Temple has also been called נוה in Jeremiah 31,22.
Chizkuni
כל אשר יגע בו הזב וגו, “anything that the person who had the emission touches, etc.” this is not really the place where this verse should have been written. It should have been written after verse 13: וכי יטהר הזב מזובו, “when the person concerned has become purified again from this contamination;” i.e. before the seven days he has to count have expired. The reason why it was written here and not there, is since the Torah had already been in the middle of dealing with this status of a person who touches ritually pure things while himself being ritually contaminated, the Torah saw fit to stick to that subject matter.
Rabbeinu Bahya
עם זו קנית, “this nation You have acquired.” Why did the Torah change from calling the Jewish people עם זו גאלת, in verse 13 to עם זו קנית? As long as Moses had spoken about the status of the Jewish people at the crossing of the Sea of Reeds when they had not yet accepted the Torah he described them as the nation whom “G’d had redeemed.” When he speaks about future events, events which would occur after the revelation at Mount Sinai, he speaks of the people G’d had acquired.
