And from now on, our words will rise like a button and flower with the commentary of the Alshech (there): "Yehuda became His sanctuary – for he sanctified the Name of Heaven, therefore he merited that Israel became Yehuda's domain, that his dominion would be over them. And he said 'to His sanctuary,' as if it were something special to him from the beginning. For this reason, we must also scrutinize his use of the word 'became,' when he should have said 'was.' However, it alludes to the fact that Yehuda continued the path of a well from which he was hewn, which is Tamar, for she sanctified the Name of Heaven by not revealing to whom she was pregnant until she was brought out to be burned (Genesis 38:25). Similarly, Yehuda sanctified the Name of Heaven by saying 'She is more righteous than I' (ibid, 26), thereby saving three lives from the fire. This is the meaning of 'became' to hint at her, and 'Yehuda' to hint at Yehuda himself, therefore it continues with 'to His sanctuary' customary to him, thus Israel became his domain." And according to our words, it means that here too, Yehuda rectified the sin of selling Yosef, by admitting the truth that the act of selling was a transgression, and he repented, thereby rectifying the sin. Thus, when Nachshon leaped into the sea, the sea split.
