1 Samuel 2:30-31
30 Wherefore the LORD God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me for ever: but now the LORD saith, Be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.
31 Behold, the days come, that I will cut off thine arm, and the arm of thy father's house, that there shall not be an old man in thine house.
Did God change His mind? (See comments on Exodus 32:14)
