Psalms 66:9

⁷ He rules forever by His power; His eyes watch the nations. Do not let the rebellious exalt themselves. Selah

⁸ Bless our God, O peoples; let the sound of His praise be heard.

He preserves our lives and keeps our feet from slipping.

¹⁰ For You, O God, have tested us; You have refined us like silver.

¹¹ You led us into the net; You laid burdens on our backs.
