Midrash

Because He delivered them across the Red Sea. So I am pleased that He will utterly destroy my captors. That's a joyful thought to me. And He will. And all the time spent waiting, is just evidence before their faces, that my God reigns. And He does. He's very real. It's one of my favorite stories, how God delivered His people. They were bitterly enslaved, but God showed great and mighty signs and wonders, and delivered them right before their enemies' faces. But, they sinned in the wilderness, after having witnessed God's deliverance. Which shows human ingratitude. Just like yours. But when that generation perished, the LORD delivered them into the Promised land by Joshua and Caleb, and sent great shakings of the land, great and fierce wasps, and delivered Israel Canaan as an inheritance. Yet, they did not destroy the inhabitants of the land, and the religion of Sin prospered, and the Jews forgot their God, and worshipped Sin, but the LORD had a few who were faithful, and did not bow the knee to Sin, and those the LORD will deliver, after when Babylon and Assyria came down, and destroyed Israel and Judah, Cyrus returned that remnant to their homes. For the righteous suffer long and endure trials too, when a nation is wicked. And through forbearance and patience, they persevere, and are awarded fruit from the Tree of Life.
