Issachar was one of the twelve tribes of Israel. They had understanding of the times and seasons. They were very sensitive to know things in the spirit. Some people say that they studied science and knew a lot of natural things but I don’t agree with that interpretation. I believe they were a very spiritual people, sensitive to God’s direction. They had some insight into things because of their sensitivity to God.
The word “Issachar” means reward, compensation, benefit, salary. They were people whose lifestyle rewarded others. Your sensitivity to God is compensation to other Christians because you are able to know things in the Spirit, able to pick up things in the Spirit. You are a blessing and a benefit to other Christians.
