The seventh day of Passover celebrates the splitting of the Reed Sea. At that time Moses and the people broke out in a song that sings:You'll bring them, you'll plant them, on the mount of Your estate…Our ancestors, explains the Midrash, did not fully understand what they were singing – indeed, God would not bring them to the land and only their children would make it there. We can fully understand something that our ancestors and the Midrash did not see. Many tried to plant themselves in God's estate, the Holy Land, but only Israel – who God planted there – is making a success of it.
