Did someone say traaaaain?
And the Religous leaders in Israel were teaching the Halakah, a perversion of GODs word.
Should have been Temple>LAW>Priests (Aarons lineage) and the people.
What they were: Synagogue >Rabbi Halakah.
all jacked up!
Truth is, because they worshiped Baal and the grove, Fire and tree worship, GOD divorced Israel BOOM!
Jeremiah 3:8 And I saw, when for all the causes whereby backsliding Israel committed adultery I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also
Israel (Northern) was taken captive by Assyria while Judah was taken captive to Babylon. they lost their GOD, their law and temple and created the synagogue, rabbi and halakah (Oral law, Talmud etc) system
THAT is why Christ was angry with Israels religious leaders in his day.
