'Lasting' in the Bible

I pray thee, forgive the transgression of thy handmaid: for Jehovah will certainly make my lord a lasting house; because my lord fights the battles of Jehovah, and evil has not been found in thee all thy days.

And it shall be, if thou wilt hearken unto all that I command thee, and wilt walk in my ways, and do that which is right in my sight, in keeping my statutes and my commandments, as David my servant did, that I will be with thee, and build thee a lasting house, as I built for David, and will give Israel unto thee.
