God gave Job prosperity with many sons, daughters, cattle and other domestic animals, and servants (compare Genesis 30:43; Deuteronomy 7:13; Psalm 107:38).
Numbers like seven and three (and 7,000 and 3,000) show the full extent of God's blessings for Job (see Job 42:13; also see Psalms 127:3–5; 128:3).
Job was the greatest man of all the people of the East: The numbers describing Job’s wealth might not be exact, but they are realistic for a wealthy man of that time (compare Nabal’s wealth in 1 Samuel 25:2).
