Obedience and Delight in God's Will

Psalms 40:6-10

My enemies have spoken evils against me: when shall he die and his name perish?

And if he came in to see me, he spoke vain things: his heart gathered together iniquity to itself. He went out and spoke to the same purpose.

All my enemies whispered together against me: they devised evils to me.

They determined against me an unjust word: shall he that sleepeth rise again no more?

For even the man of my peace, in whom I trusted, who ate my bread, hath greatly supplanted me.
