'All the Days of His Life' in the Bible

Now Solomon reigned over all the kingdoms from the [Euphrates] River to the land of the Philistines and to the border of Egypt; they brought tribute (money) and served Solomon all the days of his life.

However, I will not take the entire kingdom out of his hand; but I will make him ruler all the days of his life for the sake of My servant David, whom I chose because he kept My commandments and My statutes.

because David did what was right in the eyes of the Lord, and had not turned aside from anything that He commanded him all the days of his life, except in the matter of [the betrayal of] Uriah the Hittite.
