כֹּ֤ל פָּעַ֣ל יְ֭הוָה לַֽמַּעֲנֵ֑הוּ וְגַם־רָ֝שָׁ֗ע לְי֣וֹם רָעָֽה׃
永恆者所造的一切，都是為了祂自己；就連惡人，也是為災禍的日子而造的。
Rashi
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
even the wicked man He made, to leave him for the day of evil. All this is for His praise.
