לִשְׁלֹמֹ֨ה ׀ אֱֽלֹהִ֗ים מִ֭שְׁפָּטֶיךָ לְמֶ֣לֶךְ תֵּ֑ן וְצִדְקָתְךָ֥ לְבֶן־מֶֽלֶךְ׃
[A Psalm] of Solomon. Give the king Thy judgments, O God, and Thy righteousness unto the king's son;
Rashi on Psalms
Concerning Solomon He prayed this prayer on behalf of his son Solomon, for he foresaw with the holy spirit that he [Solomon] was destined to request of the Holy One, blessed be He, “a heart to understand, to hear judgment.”
Rashi on Psalms
Your judgments the wisdom of Your laws, which You commanded in the Torah.
