'Stedfast' in the Bible

To the Overseer, on the octave. -- A Psalm of David. Save, Jehovah, for the saintly hath failed, For the stedfast have ceased From the sons of men:

The law of Jehovah is perfect, refreshing the soul, The testimonies of Jehovah are stedfast, Making wise the simple,

And might not be as their fathers, a stubborn and rebellious generation; a generation that set not their heart aright, and whose spirit was not stedfast with God.

For their heart was not right with him, neither were they stedfast in his covenant.

To the age I keep for him My kindness, And My covenant is stedfast with him.

As the moon it is established -- to the age, And the witness in the sky is stedfast. Selah.

Thy testimonies have been very stedfast, To Thy house comely is holiness, O Jehovah, for length of days!

The works of His hands are true and just, Stedfast are all His appointments.
