“Issachar ” means reward
Issachar : I. The ninth son of Jacob and the fifth of Leah. (Genesis 30:17,18) (B.C. 1753-45) At the descent into Egypt four sons are ascribed to him, who founded the four chief families of the tribes. (Genesis 46:13; Numbers 26:23,25; 1 Chronicles 7:1) The number of the fighting men of Issachar, when taken in the census at Sinai, was 54,400. During the journey they seem to have steadily increased. The allotment of Issachar lay above that of Manasseh. (Joshua 19:17-23) In the words of Josephus, "it extended in length from Carmel to the Jordan, in breadth to Mount Tabor." This territory was, as it still is, among the richest land in Palestine. It is this aspect of the territory of Issachar which appears to be alluded to in the blessing of Jacob.
