'God of Justice' in the Bible

Therefore the Lord waits [expectantly] and longs to be gracious to you,And therefore He waits on high to have compassion on you.For the Lord is a God of justice;Blessed (happy, fortunate) are all those who long for Him [since He will never fail them].

You have wearied the Lord with your words. But you say, “In what way have we wearied Him?” In that you say, “Everyone who does evil is good in the sight of the Lord, and He delights in them,” or [by asking], “Where is the God of justice?”
