22 Ye shall not afflict any widow, or fatherless child.
23 If thou afflict them in any wise, and they cry at all unto me, I will surely hear their cry;
24 And my wrath shall wax hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.
The passion in God’s words is palpable in these verses! We have been hearing of laws and penalties that were to be applied by the Israelite judges, but now God is claiming judgment and retribution in this matter for Himself. The widow and the fatherless are not to be afflicted “in any wise,” and God will be actively listening for their cries of distress and punishing anyone who raises his hand against them.
As has already been noted in the rules related to the betrothal of women and the treatment of servants, God’s law shows a keen understanding of which people are in the most vulnerable of positions, and He is fiercely protective of them. In verse 24 He promises that He will raise up foreign armies to kill any Israelite men who abuse and take advantage of the widow and the fatherless.
And why would He do that? He explains it is to make the wives of those men widows, to make the children of those men fatherless. It all goes back to the principle of justice and retribution. If you would hurt or profit over those who lack a husband and father, then your own family will be made to lack a husband and father. Not only should we do unto others as we would have others do unto us, but also do unto others as we would have others do unto those under our care.
