Easton's Bible Dictionary (1897)/Issachar
Issachar: hired (Genesis 30:18). "God hath given me," said Leah, "my hire (Heb. sekhari)...and she called his name Issachar." He was Jacob's ninth son, and was born in Padan-aram (comp. Genesis 28:2). He had four sons at the going down into Egypt (Genesis 46:13; Numbers 26:23,25).
Issachar, Tribe of, during the journey through the wilderness, along with Judah and Zebulun (Numbers 2:5), marched on the east of the tabernacle. This tribe contained 54,400 fighting men when the census was taken at Sinai. After the entrance into the Promised Land, this tribe was one of the six which stood on Gerizim during the ceremony of the blessing and cursing (Deuteronomy 27:12). The allotment of Issachar is described in Joshua 19:17-23. It included the plain of Esdraelon (=Jezreel), which was and still is the richest portion of Palestine (Deuteronomy 33:18,19; 1 Chronicles 12:40).
The prophetic blessing pronounced by Jacob on Issachar corresponds with that of Moses (Genesis 49:14,15; comp. Deuteronomy 33:18,19).
