Passover was when the Lord killed all the first born children in Egypt but PASSED OVER the children of Israel. People can't do anything of worth for God. all our works are like filty rags to him. What the people did for God to pass over them is they obeyed Him by painting the blood of a lamb on the doorpost (which is what He commanded them to do). God chose them, they didn't chose God.
hope this helps

The Babylonian captivity was when the jews were exiled to babylon. Hope it helps
