Thou hast sent widows away empty, and the arms of the fatherless have been broken.
Empty - without their wants being relieved (Genesis 31:42). The Mosaic law especially protected the widow and fatherless (Exodus 22:22); the violation of it in their case by the great is a complaint of the prophets (Isaiah 1:17).
Arms - supports, helps on which one leans (Hosea 7:15, "I have strengthened their arms"). Thou hast robbed them their only stay. Job replies in Job 29:11-16.
