'Age abiding' in the Bible

And, when David heard of it, after that, he said - Guiltless, am I and my kingdom before Yahweh, unto times age-abiding, - of the blood of Abner son of Ner.

He, shall build a house for my name, - and I will establish his kingly throne unto times age-abiding:

So shall thy house and thy kingdom be made steadfast unto times age-abiding, before thee, - thy throne, shall be established unto times age-abiding.

and hast established for thyself thy people Israel - for thyself as a people, unto times age-abiding, - thou thyself, also, O Yahweh, becoming their God.

Now, therefore, O Yahweh Elohim, the word which thou hast spoken concerning thy servant, and concerning his house, confirm thou, unto times age-abiding, - and do, as thou hast spoken:

Now, therefore, the sword shall not depart from thy house, unto age-abiding times, - because thou hast despised me, and taken the wife of Uriah the Hittite to be thy wife.

Who hath made great the victories of his King, - and shown lovingkindness to his Anointed One, to David and to his Seed, unto times age-abiding.

When, not so, was my house with GOD, Then, a covenant age-abiding, he appointed me, Ordered in all things and guarded, Now that it is all my salvation and all my desire, Will he not make it shoot forth?
