Mishná sobre Juízes 1:9

There are three territories in respect to the law of removal [of sheviit produce]: [these are]: Judea, Transjordan, and Galilee, and there are three territories in each one. Upper Galilee, lower Galilee, and the valley. From Kefar Hananiah upwards, the region where sycamores do not grow, is Upper Galilee. From Kefar Hananiah downwards, where the sycamores do grow, is Lower Galilee. The borders of Tiberias are the valley. Those of Judea are: the mountain region, the plains [of the south], and the valley. The plains of Lod are like the plains of the south, and its mountain region is like the king's hill-country. From Bet Horon to the sea is considered as one land.
