כֹּ֣ה ׀ אָמַ֣ר יְהוָ֗ה אַל־יִתְהַלֵּ֤ל חָכָם֙ בְּחָכְמָת֔וֹ וְאַל־יִתְהַלֵּ֥ל הַגִּבּ֖וֹר בִּגְבֽוּרָת֑וֹ אַל־יִתְהַלֵּ֥ל עָשִׁ֖יר בְּעָשְׁרֽוֹ׃
Так говорит Господь: да не превозносит мудрый человек мудрости своей, и пусть не превозносится могучий человек славою своей, да не превозносится богатый человек славою своим;
Tze'enah Ure'enah
“Thus says the Lord, let not the wise man glory in his wisdom” [9:22]. God said: no person should boast, even when he is very rich or wise. When the Holy One does not want to help, then his wisdom is nothing. Similarly, if he is a hero, he should not boast of his heroism. Similarly, when he is rich, he should not boast of his wealth, but he should rely on the Holy One.
Rashi
Let not the wise man boast Do not boast, saying, “We are wise.” Behold, you have rejected My words, so what wisdom do you have? If you understand and know Me, then you can boast of your wisdom.
