Sustenance

From this morning's readings:

Psalm 3:5
I lay down and slept; I awoke, for the LORD sustains me.

Psalm 4:7
You have put gladness in my heart, More than when their grain and new wine abound.

Psalm 5:3
In the morning, O LORD, You will hear my voice; In the morning I will order my prayer to You and eagerly watch.
