Rashi on Psalms
One who slaughters a confession sacrifice [One] who brings Me a sacrifice of repentance and confession for his iniquities, honors Me.
Rashi on Psalms
and [I will] prepare the way for the one who returns to Me. I teach and prepare the way for sinners to return to Me (and he who returns to Me—Shem Ephraim), I will show him My salvation.
