Genesis 42:33-34

ISV(i) 33 But the man who was in charge of the land responded, ‘I’m going to test your honesty. Leave one of your brothers with me, take some grain for the famine that’s afflicting your households, and leave. 34 But bring your youngest brother back to me so I can be sure that you’re honest men, and not spies. Then I’ll return your brother to you, and you’ll be allowed to trade anywhere in the land.’”
