'Stedfast' in the Bible

and I have raised up for Me a stedfast priest; as in My heart and in My soul he doth do; and I have built for him a stedfast house, and he hath walked up and down before Mine anointed all the days;

Bear, I pray thee, with the transgression of thy handmaid, for Jehovah doth certainly make to my lord a stedfast house; for the battles of Jehovah hath my lord fought, and evil is not found in thee all thy days.
