At the Constitutional Convention of 1787, James Madison proposed the plan to divide the central government into three branches. He discovered this model of government from the Perfect Governor, as he read Isaiah 33:22;
"For the LORD is our judge, the LORD is our lawgiver, the LORD is our king; He will save us."
This is the birth of the branches of government.
