David is so sure the Lord God will not only hear him but also grant what he is asking. So now, he considers himself in debt to pay his vow to the Lord God regarding what he would do once he is granted his request.

Jesus gave his life freely so I could be pardoned and gain eternal life through him and in him. He said, “Freely you have received, freely give.” (Matthew 10:8) He also said, “I have set you an example that you should do as I have done to you.” (John 13:15) As Jesus told the woman who was caught in the act of adultery and forgiven by him, “Go now and leave your life of sin” (John 8:11)
