Deuteronomy 24:6 - Coke's Commentary on the Holy Bible

Ver. 6. No man shall take the nether or the upper millstone to pledge— This law is of the same merciful kind with that in Exodus 22:26-27 which is repeated in the following verses; and it is founded upon the same equitable and compassionate reasons. On the same account it was, that at Rome they were forbidden to take the oxen or plough of a labourer, for the payment of his debts; and there is the same humane provision in our laws also, which prohibit the distraining of a labouring man's working tools or implements. See Blackstone's Commentaries, Book 3: ch. 1.
