Psalms 43:5

‘Why are you cast down, O my soul?

And why are you disquieted within me?

Hope you in God,

For I will yet praise him,

Who is the help of my countenance,

And my God.'

This final truth has confirmed his faith and made him sure of his deliverance. Thus he can with even more confidence call on his soul and ask it why is it so disquieted simply because of these troubles that have beset him. Let it hope in God. For he knows that God must eventually release him so that he may yet go to the House of God to praise Him, for God is the one who is his constant aid and sustainer, and is his God.

As mentioned above, the fact that we have this psalm is an indication that God did eventually deliver him.
