1 Samuel 17:28 When Eliab, David’s oldest brother, heard him speaking with the men, he burned with anger at him and asked, “Why have you come down here? And with whom did you leave those few sheep in the wilderness? I know how conceited you are and how wicked your heart is; you came down only to watch the battle.” 
When I do what the Lord asks of me, there will be people who do not understand. Lord, enable me to do Your will in the face of adversity against giants I don’t know, as well as giants I do know.
