'Stedfast' in the Bible

for if the word being spoken through messengers did become stedfast, and every transgression and disobedience did receive a just recompense,

wherefore it did behove him in all things to be made like to the brethren, that he might become a kind and stedfast chief-priest in the things with God, to make propitiation for the sins of the people,

being stedfast to Him who did appoint him, as also Moses in all his house,

and Moses indeed was stedfast in all his house, as an attendant, for a testimony of those things that were to be spoken,

which we have, as an anchor of the soul, both sure and stedfast, and entering into that within the vail,

for a covenant over dead victims is stedfast, since it is no force at all when the covenant-victim liveth,
