תהילים צט:ד פירוש: רש״י

and the might of the King Who loves judgment This refers back to the preceding verse.

You founded equity You founded compromise and peacemaking between persons, by Your statement (Exod. 23:5): “Should you see your enemy’s donkey lying etc.”; (ibid. verse 4), “Should you come upon Your enemy’s ox, etc.” Now who is it who sees his enemy being kind to him, whose heart will not be inspired to embrace him and kiss him? (Tanchuma).
