כֹּ֤ל פָּעַ֣ל יְ֭הוָה לַֽמַּעֲנֵ֑הוּ וְגַם־רָ֝שָׁ֗ע לְי֣וֹם רָעָֽה׃
L’Éternel a tout fait pour un but prédestiné, même le méchant pour le jour du malheur.
Rashi on Proverbs
The Lord made everything for His praise Heb. למענהו. He made everything for His praise, as in (Ps. 147:7): “Praise (ענו) the Lord with thanksgiving.” Another explanation: To testify concerning Him. That is to say that His work testifies concerning Him, about His mighty acts. Both are in the Aggadah of Psalms (Midrash Tehillim 19:1).
Rashi on Proverbs
even the wicked man He made, to leave him for the day of evil. All this is for His praise.
