Wholesale theft happens everywhere, but when the shelves are empty and no more food to buy then what will you do to help feed you and your family?
In this mans case in the OP he tried to find wild game, but when there was none, he reached out in faith and prayed to God for the needs of his family. When this calf wondered over to him and nudged him, I can only believe this was God's answer to his prayer. Even though the calf belonged to the farmer I do not see it as stealing the calf, but God providing for the needs of his family. We know the commandment, do not steal, but I do not see this act as stealing.
No one truly knows what they will do when desperate times will fall upon all of us and the stores have no more food. One should stockpile, but also to stockpile to help others that can not.
