'Maintain' in the Bible

You keep completely safe the people who maintain their faith, for they trust in you.

For this is what the LORD says: "Maintain justice, and do what is right, for soon my salvation will come, and soon my deliverance will be revealed.

For the sake of Zion I will not be silent, and for the sake of Jerusalem I will not maintain a quiet attitude, until her righteousness goes out like the bright light, and her salvation burns like a torch.
