דּ֤וֹם ׀ לַיהוָה֮ וְהִתְח֪וֹלֵ֫ל ל֥וֹ אַל־תִּ֭תְחַר בְּמַצְלִ֣יחַ דַּרְכּ֑וֹ בְּ֝אִ֗ישׁ עֹשֶׂ֥ה מְזִמּֽוֹת׃
Resign thyself unto the LORD, and wait patiently for Him; fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.
Read halakhic rulings (Jewish law) on Psalms 37:7: and classical halakhic sources.
