Looking Downwards

Why my soul are you downcast? Why so disturbed within me? Put your hope in God, for I will yet praise Him, my Saviour and my God. Psalm 42:11

What’s the difference between ‘cast down’ and’downcast?’ External circumstances can cause us to be cast down, while the dictionary tells me ‘downcast’ means, looking downwards and dejected. This is something we can bring on ourselves. Therefore we do need to praise God and not look down.
