'Faithfulness' in the Bible

And righteousness hath been the girdle of his loins, And faithfulness -- the girdle of his reins.

Like myself to-day -- a father to sons Doth make known of Thy faithfulness, O Jehovah -- to save me: And my songs we sing all days of our lives In the house of Jehovah.'

There is none calling in righteousness, And there is none pleading in faithfulness, Trusting on emptiness, and speaking falsehood, Conceiving perverseness, and bearing iniquity.

So that he who is blessing himself in the earth, Doth bless himself In the God of faithfulness, And he who is swearing in the earth, Doth swear by the God of faithfulness, Because the former distresses have been forgotten, And because they have been hid from Mine eyes.
