Exodus 31-34

God said that he would lead his people in the displacement of those who currently control the Promised Land. Then he told Israel that for three separate weeks out of each year all of the men were to leave their newly acquired inheritance and appear before him with gifts. The men whom God would use to over throw bigger and stronger nations would leave their new homes, the ones they didn't build, empty. They would leave their harvests in their barns and travel some unknown distance to spend a week in celebration with God's people. In Exodus 34:23-24 God promised Israel that for those three weeks each year he would protect their homes and harvests. That was a powerful display of faith.
