Psalms 7:12

¹⁰ My shield is with God, who saves the upright in heart.

¹¹ God is a righteous judge and a God who feels indignation each day.

If one does not repent, God will sharpen His sword; He has bent and strung His bow.

¹³ He has prepared His deadly weapons; He ordains His arrows with fire.

¹⁴ Behold, the wicked man travails with evil; he conceives trouble and births falsehood.

Do read the surrounding verses too, because the context often says more than a single verse.
