Continuing the story of David and Goliath

[Saul] If you plan to fight this giant You must depend on this reliant Helmet, armor, and our best sword You'll be protected, that's my word!

[David] I can't move, it's too excessive How then can I be aggressive? Every step a stumbling block How can I fight if I cannot walk?

I tell you, I have got this thing A few small stones, my trusted sling I will return the victor yet I will overcome the giant's threat

[Saul] Then go with God, right at your side Your victory cannot be denied Bring back your prize and you'll receive Your faith in God makes me believe
