'Confirmed' in the Bible

And David perceived that the LORD had confirmed him king over Israel, for his kingdom was lifted up on high, because of his people Israel.

And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,

Now, Lord, let the word that You have spoken concerning Your servant and his house be confirmed forever, and do as You have promised.

Let Your name be confirmed and magnified forever in the saying, “Yahweh of Hosts, the God of Israel, is God over Israel.” May the house of Your servant David be established before You.
