'Lasting' in the Bible

But I will raise up for myself a reliable priest; he will do just according to what [is] in my heart and in my soul. I will build for him a lasting house and he will walk continually before my anointed one {forever}.

Please forgive the transgression of your female servant, because Yahweh will certainly make a lasting house for my lord, because my lord [is] fighting the battles of Yahweh, and evil will not be found in you {as long as you live}.
