'Faith in the Lord' in the Bible

So at that time the children of Israel were overcome, and the children of Judah got the better of them, because they put their faith in the Lord, the God of their fathers.

And early in the morning they got up and went out to the waste land of Tekoa: and when they were going out, Jehoshaphat took his station and said to them, Give ear to me, O Judah and you people of Jerusalem: have faith in the Lord your God and you will be safe; have faith in his prophets and all will go well for you.
