Starts with God calling for Israel to return to Him, an appeal for their repentance to receive His response that was promised in verses 4-8.
“Return, O Israel, to the Lord your God. Your sins have been your downfall!” (v1)Psalm 130:7-8 O Israel, hope in the Lord! For with the Lord there is steadfast love, and with him is plentiful redemption. And he will redeem Israel from all his iniquities.
