Their mother was Leah, sister of Rachel.
The color of the standard of Issachar was dark blue "close to black".
The stone of Issachar is described as a "sapir" meaning sapphire.The Standard of Issachar depicted the sun, moon, and stars.
The Children of Issachar traditionally had the task of determing the Hebrew Calendar which involved astronomical calculations
while taking account of agricultural seasons and community convenience: There were certain days when
celebrating a feast day would have disrupted the public so these days had to be avoided yet chronological
and solar-seasonal consistency maintained. He was symbolized by a donkey. He was born when his mother, Leah, "hired" her husband from
Rachel for the night. The name Issachar is derived from the root "sachar" meaning "hiring" and this embodies
aspects of the Characteristics of Issachar.
