"He had seven sons and three daughters, and he owned seven thousand sheep, three thousand camels, five hundred yoke of oxen and five hundred donkeys, and had a large number of servants. He was the greatest man among all the people of the East." NIV translation
The author goes on to introduce us to Job by describing the fact that he was truly blessed and we are reminded that the simple definition of "blessed" is "worry free". We see that he had seven sons and that number is associated with completeness as well as three daughters with that number being associated with the display of God's will. This man had a growing family and did not have to worry about whether his name would live on after he died.
We also see that he was blessed materially more than all of the other men in the East. This was a man that did not have to bear the daily worry of wondering how he was going to feed his family.
The "people of the East" refers to the people that lived in the desert that is located to the east of Jerusalem as all biblical directions are based on Jerusalem at the center.
In short, life was looking good for this man of God but little did he know that he was about to face the darkest of nights.
"His sons used to hold feasts in their homes on their birthdays, and they would invite their three sisters to eat and drink with them. When a period of feasting had run its course, Job would make arrangements for them to be purified. Early in the morning he would sacrifice a burnt offering for each of them, thinking, 'Perhaps, my children have sinned and cursed God in their hearts.' This was Job's regular custom." NIV translation
The man was blessed in many ways but we see that his main worry was for his children and their relationship with the Lord. They would get together for parties that could last for up to a week and, when it was over, Job would present burnt offerings on their behalf just in case they had sinned during that time. The death of the animals in the sacrifices was a picture of Christ the Redeemer and the fact that He paid the price for all of man's sins. This was a demonstration of the depth of the man's faith as he took his fears directly to God and we are reminded that the best preparation for the dark night of trials in our faith is to have a solid relationship with the Lord while the sun is shining.
