In the seventh aliyah the Jews approach the land of Sichon and send a message to its king asking permission to pass through in peace. The King refuses and comes out with an army to attack the Jews. The Jews fight them and win, and occupy their land. Later the king of Bashan, named Og, attacks the Jews. As a result the Jews kill King Og and occupy his land also.
At this point the Jewish nation has reached the bank of the Jordan River, just across from the city of Jericho in the land of Israel.
