Psalm 40

I've never had much direct contact with sheep, but I understand that they can get themselves in situations where all they can do is start bleeting and crying out. I wonder if there was a day that young David heard the fearful call of a sheep over a hill? When he crossed the rise he saw one of his flock up to him belly in a bog; worn out from the struggle crying out in hope that his shepherd would save him. David might have slipped off his sandals and waded into the muck to retrieve the wayward animal. He would have to raise him high and carry him until they reach solid footing. Then setting the his sheep on the rocky soil he would retrieve is footwear and they would rejoin the rest of the flock. I see that story in the first 3 verses of this psalm and the lesson that young shepherd learned in the last 2.
It took me about 4 minutes to read this song of David.
