As the priest and religious leader of his household, when their days of feasting were over, Job would send for them and sanctify them through burnt offerings and prayers. He offered sacrifices to God (one burnt offering per child) asking forgiveness for any sin or lasciviousness they may have committed at their parties.
Job feared God and shunned evil, and was afraid his children may have blasphemed or behaved profanely against God. Job had many servants and I am sure they were able to give him certified details of the ongoings of his children. They were always giving Job a reason to pray. They were ungodly and Job knew it.
As a result of Job's prayers, God decided that He wanted to bless Job with new children that would produce a lineage of godly sons and daughters that feared and respected God as their father Job did. So, when Satan came around confessing that he had been going here and there on the earth, God presented Job to Satan, and removed the hedge of protection that had been preventing Satan's attacks on Job.
On a day when Job's children were celebrating at their oldest brother's house, Satan sent a tornado and it demolished the house which collapsed and killed all ten of Job's children.
During Job's trials he had lost everything (all his livestock, his health, and his children). God restored all Job's losses giving him back twice as much as he had before.
God also gave Job seven more sons and three more daughters. BUT... these children were not the same as those that died. These were as God fearing as their father Job was, and were beautiful inside and outside. Job did not have to offer burnt offerings as a result of lewd and lascivious behavior. These ten children produced beautiful generations of godly children that Job was able to enjoy and leave an inheritance to. The Lord let Job live 140 more years to enjoy seeing his family up to his great, great grandchildren, then he died being old and full of days.
James 5:11 (NKJV) Indeed we count them blessed who endure. You have heard of the perseverance of Job and seen the end intended by the Lord - that the Lord is very compassionate and merciful.
To God be the glory.
