What does 1 Kings 11:31 mean?

Then Ahijah said to Jeroboam, 'Take ten pieces for yourself. The Lord, the God of Israel, says, “I’m going to tear the kingdom out of Solomon’s hand and give you ten tribes.”' 1 Kings 11:31 - Modern Text Bible

(Ahijah’s message was clear: God was about to split the kingdom, giving most of it to Jeroboam as a result of Solomon’s unfaithfulness.)
