Israel and Judah have a split in two vibe. Israel is the original land of milk and honey promised to Abraham as a place to settle his mighty army of descendents.
The vibe remains pretty good and Israel is home to the Israelites until King Solomon dies. Solomon has turned his back on God and as soon as he’s dead, the bubble bursts. There is a big falling out between the Twelve Tribes: two of them want Solomon’s son as king and the rest don’t. The ones that do set up the kingdom of Judah and the ones that don’t stay put in Israel.
Judah gets to keep Jerusalem and the two countries fight constantly until Israel is trounced by Assyria. Judah lingers on for another 130 years until it is beaten soundly by the Babylonians who destroy Jerusalem and drag the people off as prisoners.
Around forty years later it’s time up for Babylon as it gets a good bashing from Persia which also wipes out the Assyrians who are still squatting in what used to be Israel. Finally, the Roman army under Pompey defeats the Persians and the whole area is split into Galilee, Samaria and Judea. Around Zero BC, Jesus is born in Nazareth in the region of Galilee and the rest, my friends, is history.
General vibe of Israel and Judah: Divide and be conquered.
Factvibe: Judah is named after one of Jacob’s twelve sons whose family lived there.
