The Kingdom
The Kingdom Divided
Rehoboam answered the people harshly, ten tribes walked away, and the kingdom never came back together. 1 Kings 12:1–24
From here on, Israel means the ten tribes in the north and Judah means the two in the south. The distinction matters more than it looks: every promise about the Messiah was made to the line of David, who ruled in Judah. The northern tribes had no claim on those prophecies at all.
Why it could never be put back together
The reason the nation could never again be reconciled is that the northern kingdom, led by evil kings, started a rival religion — the worship of golden bulls as their God. A clear reaching back to the god of Egypt. The two could never be reconciled.
That is not a paraphrase of Aaron at Sinai. It is the same sentence: “Israel, here are your gods who brought you out of Egypt” (Exodus 32:4).
And Jeroboam had just come back from there. He had fled to Egypt from Solomon and was still living there when the tribes sent for him (I Kings 12:2) — a land where the bull was worshipped. He returned, and built his kingdom on the sin Israel had already been forgiven once.
It held to the end. Every northern king after him kept the calves, and when the account of the north closes, this is the reason given for it:
“Jeroboam forced Israel away from the LORD and led them to commit a serious sin. The Israelites followed all the sins Jeroboam committed and never turned away from them. … So the people of Israel were taken from their land to Assyria as captives.”II Kings 17:21–23 · GW
