'Stedfastness' in the Bible

O Jehovah, my God art Thou, I exalt Thee, I confess Thy name, For Thou hast done a wonderful thing, Counsels of old, stedfastness, O stedfast One.

Open ye the gates, that enter may a righteous nation, Preserving stedfastness.

And hath been the stedfastness of thy times, The strength of salvation, wisdom, and knowledge, Fear of Jehovah -- it is His treasure.
