עִ֣יר קְטַנָּ֔ה וַאֲנָשִׁ֥ים בָּ֖הּ מְעָ֑ט וּבָֽא־אֵלֶ֜יהָ מֶ֤לֶךְ גָּדוֹל֙ וְסָבַ֣ב אֹתָ֔הּ וּבָנָ֥ה עָלֶ֖יהָ מְצוֹדִ֥ים גְּדֹלִֽים

There was a little city, with few men in it; and to it came a great king, who invested it and built mighty siege works against it.

וּמָ֣צָא בָ֗הּ אִ֤ישׁ מִסְכֵּן֙ חָכָ֔ם וּמִלַּט־ה֥וּא אֶת־הָעִ֖יר בְּחָכְמָת֑וֹ וְאָדָם֙ לֹ֣א זָכַ֔ר אֶת־הָאִ֥ישׁ הַמִּסְכֵּ֖ן הַהּֽוּא

Present in the city was a poor wise man who might have saved it with his wisdom, but nobody thought of that poor man. 

וְאָמַ֣רְתִּי אָ֔נִי טוֹבָ֥ה חָכְמָ֖ה מִגְּבוּרָ֑ה וְחָכְמַ֤ת הַמִּסְכֵּן֙ בְּזוּיָ֔ה וּדְבָרָ֖יו אֵינָ֥ם נִשְׁמָעִֽים

So I observed: Wisdom is better than valor; but A poor man’s wisdom is scorned, And his words are not heeded.
