Dinner with joseph

Last time we learned that a widespread famine had swept the land, Jacob sent his sons to Egypt to buy grain. When the brothers arrived, they bowed before the governor, not realizing it was Joseph, the brother they had sold into slavery two decades before. He accused them of being spies. (Gen. 42:14-15). This is the first of two critical tests. The next one occurs in Genesis 44. So, why did Joseph consider it necessary to test his brothers? Hold that question, and I will answer it next time.
