“Woe to those who decree iniquitous decrees, and the writers who keep writing oppression, to turn aside the needy from justice and to rob the poor of my people of their right, that widows may be their spoil, and that they may make the fatherless their prey!” (v1-2). God brought Israel out of Egypt, put them in the Promised Land and blessed them, yet they disregarded His laws and used their power to oppress “the needy” and the fatherless. Isaiah warned Israel that God’s day of punishment coming (v3).
Our gifts aren’t our own. God’s blessings and favor, “a fruitful land” (v18), are given so that we can bless others, showing mercy and glorifying Him.
