Psalm 3

It was a desperate time in which David found himself embroiled as he sang out these words to God. Whenever David faced a change in life, be it good or bad, he began to sing. The faith behind his words is evident in verse 5; for he was able to lay down and sleep. We all need rest, but when anxieties are many sleep is not close by. So for David to sleep shows a wonderful trust that God was not through with him. It reminds of Peter who centuries later would sleep peacefully on the jail floor the night before he was to be killed. The angle had to kick Peter's side in order to interupt his rest. Peter, like David understood what God could do to rescue his people from their deaths.
It took me about 1 minute to read this psalm.
