Psalm 46 New International Version (NIV)

Psalm 46^[a]

For the director of music. Of the Sons of Korah. According to alamoth.^[b] A song.

¹God is our refuge and strength,
    an ever-present help in trouble.
²Therefore we will not fear, though the earth give way
    and the mountains fall into the heart of the sea,
³though its waters roar and foam
    and the mountains quake with their surging.^[c]

⁴There is a river whose streams make glad the city of God,
    the holy place where the Most High dwells.
⁵God is within her, she will not fall;
    God will help her at break of day.
⁶Nations are in uproar, kingdoms fall;
    he lifts his voice, the earth melts.

⁷The Lord Almighty is with us;
the God of Jacob is our fortress.

⁸Come and see what the Lord has done,
    the desolations he has brought on the earth.
⁹He makes wars cease
    to the ends of the earth.
He breaks the bow and shatters the spear;
    he burns the shields^[d] with fire.
¹⁰He says, “Be still, and know that I am God;
    I will be exalted among the nations,
    I will be exalted in the earth.”

¹¹The Lord Almighty is with us;
the God of Jacob is our fortress.

Psalm 23 New International Version (NIV)

A psalm of David.

1
The Lord is my shepherd, I lack nothing.
2
He makes me lie down in green pastures,
he leads me beside quiet waters,
3
he refreshes my soul.
He guides me along the right paths
for his name’s sake.
4
Even though I walk
through the darkest valley,[a] I will fear no evil,
for you are with me;
your rod and your staff,
they comfort me.

5
You prepare a table before me
in the presence of my enemies.
You anoint my head with oil;
my cup overflows.
6
Surely your goodness and love will follow me
all the days of my life,
and I will dwell in the house of the Lord
forever.
