'Established' in the Bible

But I will settle him in mine house and in my kingdom for ever: and his throne shall be established for evermore.

Therefore now, LORD, let the thing that thou hast spoken concerning thy servant and concerning his house be established for ever, and do as thou hast said.

Let it even be established, that thy name may be magnified for ever, saying, The LORD of hosts is the God of Israel, even a God to Israel: and let the house of David thy servant be established before thee.
