以萨迦（יִשָּׂשׁכָר 标准希伯来语Yissaḫar, Tiberian希伯来语Yiśśâḵār）是雅各和他第一任妻子利亚的第五个儿子。按照创世记，以萨迦是利亚用她的大儿子流便寻见的风茄向拉结交换来与丈夫同床一夜的权利，她对雅各说，我用我儿子的风茄把你雇下了，你要与我同寝。所以利亚给生下的这个孩子起名以萨迦，意思是工价。他的后代以萨迦支派是以色列十二支派之一，住在加利利海东南。创世记49章，他父亲雅各在埃及临终前为他祝福"以萨迦是个强壮的驴，卧在羊圈之间。他看安息之处为佳，看那地为美，便低肩背重，成为服苦的仆人。"

Issachar/Yissachar (Hebrew: יִשָּׂשכָר, Modern Yissakhar, Tiberian Yiśśāḵār ; "reward; recompense") was, according to the Book of Exodus, a son of Jacob and Leah (the fifth son of Leah, and ninth son of Jacob), and the founder of the Israelite Tribe of Issachar; however some Biblical scholars view this as postdiction, an eponymous fortson I providing an aetiology of the connectedness of the tribe to others in the Israelite confederation. The text of the Torah gives two different etymologies for the name of Issachar, which some textual scholars attribute to different sources - one to the Yahwist and the other to the Elohist; the first being that it derives from ish sakar, meaning man of hire, in reference to Leah's hire of Jacob's sexual favours for the price of some mandrakes; the second being that it derives from yesh sakar, meaning there is a reward, in reference to Leah's opinion that the birth of Issachar was a divine reward for giving her handmaid Zilpah to Jacob as a concubine. Scholars suspect the former explanation to be the more likely name for a tribe, though some scholars have proposed a third etymology - that it derives from ish Sokar, meaning man of Sokar, in reference to the tribe originally worshipping Sokar, an Egyptian deity.
