Genesis 30:18

New International Version

Then Leah said, “God has rewarded me for giving my servant to my husband.” So she named him Issachar.

See the chapter Copy

from Issachar, men who understood the times and knew what Israel should do—200 chiefs, with all their relatives under their command;

About Zebulun he said: “Rejoice, Zebulun, in your going out, and you, Issachar, in your tents.

The sons of Issachar: Tola, Puah, Jashub and Shimron.

The sons of Leah: Reuben the firstborn of Jacob, Simeon, Levi, Judah, Issachar and Zebulun.

God listened to Leah, and she became pregnant and bore Jacob a fifth son.

Leah conceived again and bore Jacob a sixth son.
