"And the LORD restored Job's losses when he prayed for his friends, indeed the LORD gave Job twice as much as he had before. Then all his brothers, all his sisters, and all those who had been his acquaintances before, came to him and ate food with him in his house; and they consoled him and comforted him for all the adversity that the LORD had brought upon him. Each one gave him a piece of silver and each a ring of gold. Now the LORD blessed the latter days of Job more than his beginning; for he had fourteen thousand sheep, six thousand camels, one thousand yoke of oxen, and one thousand female donkeys. He also had seven sons and three daughters. And he called the name of the first Jemimah, the name of the second Keziah, and the name of the third Keren-Happuch. In all the land were found no women so beautiful as the daughters of Job; and their father gave them an inheritance among their brothers. After this Job lived one hundred and forty years, and saw his children and grandchildren for four generations. So Job died, old and full of days" (Job 42:10-17).
It is important to note that Job's fortunes were only restored when he prayed for his friends. Observe Job's tremendous character here. He would not allow himself to be filled with bitterness and hostility toward those who had crushed him verbally time and again. Job is too great of a man to hold a grudge! On a couple occasions, Job had mentioned that the friends were worse off than him because of their flawed theology (cf. 13:7-12; 19:28,29). He now has an opportunity to express his love for them by praying for them. The Lord still loves Job very much and restores his possessions two-fold. Even today there are blessings from God that will not be received if our hearts are bitter against those who have wronged us (cf. Matt. 6:14,15).
The family members and friends who had formerly deserted Job now come to console, comfort him, and give him gifts. Even when someone is recovering from devastating loss, there is still ministering to be done. Certainly Job's heart still ached for his deceased children. Yet God blessed him with more children also! It is unknown as to why the names of the daughters are listed but not the names of the sons. Perhaps it is because of the unusual practice mentioned in Job 42:15; that is, giving the daughters an inheritance among the sons.
Because God restored Job's possessions two-fold, some speculate that Job lived to be 210 years old (70 before + 140 after). This life span is consistent with the age of the patriarchs who lived just prior to Abraham (cf. Gen. 11). Job 42:16 specifically states that Job lived 140 years more after his suffering. Whether he was approximately 70 years old when the book begins is impossible to prove, but it is certainly possible. Regardless of how old the great patriarch was when he passed on from this realm, he died very content and happy.
Back in Job 1:21, Job stated - "The LORD gave and the LORD has taken away." Now the Lord has given again! Truly, Job has gone from tragedy to triumph and he did it because of his strong faith in God Almighty! May we learn from Job and follow his example!
