With God we will gain the victory, for the help of man is worthless

Psalm 108
My heart is steadfast, O God; I will sing and make music with all my soul.
I will praise you, O Lord, among the nations; I will sing of you among the peoples. For great us your love , higher than the heavens; your faithfulness reaches to the skies.
Give us aid against the enemy, for the help of man is worthless. With God we will gain the victory, and he will trample down our enemies.
