Psalm 63:9-11

Amplified Bible

⁹ 
But those who seek my life to destroy it
Will [be destroyed and] go into the depths of the earth [into the underworld].
¹⁰ 
They will be given over to the power of the sword;
They will be a prey for foxes.
¹¹ 
But the king will rejoice in God;
Everyone who swears by Him [honoring the true God, acknowledging His authority and majesty] will glory,
For the mouths of those who speak lies will be stopped.
