Thanks for your question.
There are two Issachars mentioned in the Bible:
- The ninth son of Jacob and the fifth of those born to Leah. See Genesis 30:18. He was one of the patriarchs of the 12 tribes of Israel.
- The son of Obededom, a gatekeeper in David's sanctuary. See 1 Chronicles 26:5
I hope you have found this helpful.
God bless you,
