Philippians 4:4-6 (ESV)
4 Rejoice in the Lord always; again I will say, rejoice. 5 Let your reasonableness be known to everyone. The Lord is at hand; 6 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
Psalm 13 (ESV)
How Long, O Lord?
To the choirmaster. A Psalm of David.
13 How long, O Lord? Will you forget me forever?
How long will you hide your face from me?
2 How long must I take counsel in my soul
and have sorrow in my heart all the day?
How long shall my enemy be exalted over me?
3 Consider and answer me, O Lord my God;
light up my eyes, lest I sleep the sleep of death,
4 lest my enemy say, “I have prevailed over him,”
lest my foes rejoice because I am shaken.
5 But I have trusted in your steadfast love;
my heart shall rejoice in your salvation.
6 I will sing to the Lord,
because he has dealt bountifully with me.
