Charles Ellicott Commentary Jeremiah 7:6

"if ye oppress not the sojourner, the fatherless, and the widow, and shed not innocent blood in this place, neither walk after other gods to your own hurt:" — Jeremiah 7:6 (ASV)

The stranger, the fatherless, and the widow. —Grouped together, as in Deuteronomy 14:29; Deuteronomy 24:19–21, as the three great representatives of the poor and helpless, therefore standing most in need of human justice and of the divine protection.
