לְדָוִ֨ד ׀ אַל־תִּתְחַ֥ר בַּמְּרֵעִ֑ים אַל־תְּ֝קַנֵּ֗א בְּעֹשֵׂ֥י עַוְלָֽה׃
Von David. Erhitze dich nicht über die Bösewichter, ereifere dich nicht über die, welche Unrecht tun.
Rashi on Psalms
Do not compete with the evildoers He reproves Israel that they should not compete with the success of the evildoers to do as their deeds, as (in Jer. 12:5): “how will you compete (תתחרה) with horses,” to run as they run, a atir in Old French, to compete.
Rashi on Psalms
do not envy those who commit injustice to commit injustice like them.
