Chp. 21 verses 20 - 35: Continues with the song of praise to Hashem. Moshe sends messengers to Sichon the king of the Amorites to allow them to pass through his land. He refuses and attacks them. He is defeated and all his lands are taken by the Jews. They then turn their attention to Og the king of Bashan and Hashem tells Moshe not to fear him. He too is defeated and his lands are possessed by the Jewish nation.
