The chief jailer did not have to look after anything that was in Joseph’s charge, since the Lord was with him and was bringing success to whatever he was doing.
From the moment that he put him in charge of his household and all his possessions, the Lord blessed the Egyptian’s house for Joseph’s sake; the Lord’s blessing was on everything he owned, both inside the house and out.
Bring the whole tithe into the storehouse, That there may be food in my house. Put me to the test, says the Lord of hosts, And see if I do not open the floodgates of heaven for you, and pour down upon you blessing without measure!
