I lie awake thinking of you,
    meditating on you through the night.
⁷ Because you are my helper,
    I sing for joy in the shadow of your wings.
⁸ I cling to you;
    your strong right hand holds me securely.

⁹ But those plotting to destroy me will come to ruin.
    They will go down into the depths of the earth.
¹⁰ They will die by the sword
    and become the food of jackals.
¹¹ But the king will rejoice in God.
    All who swear to tell the truth will praise him,
    while liars will be silenced. Psalm 63:6-11
