Musar sobre Lamentaciones 5:8

The reason that in the Bible the Holy Land is referred to as the land of Canaan quite often even after the Jewish people took possession of it, is that Canaan was the first "slave" (Genesis 9,25). The word כנען also is derived from the word כנען, submission. The message to Israel in all this is that as long as they submit to the will of G–d the land remains theirs. When the people rejected their status as servants of G–d, they became slaves of the nations instead.
