Psalms 108:12

¹⁰ Who will bring me to the fortified city? Who will lead me to Edom?

¹¹ Have You not rejected us, O God? Will You no longer march out, O God, with our armies?

Give us aid against the enemy, for the help of man is worthless.

¹³ With God we will perform with valor, and He will trample our enemies.
