John Gill Commentary Isaiah 47:6

"I was wroth with my people, I profaned mine inheritance, and gave them into thy hand: thou didst show them no mercy; upon the aged hast thou very heavily laid thy yoke." — Isaiah 47:6 (ASV)

I was wroth with my people The people of Israel, for their sins and transgressions, particularly their idolatries. Here begin the reasons and causes of the destruction of Babylon, and the first mentioned is their cruelty to the people of God; for though he was angry with them himself, yet he resented their being ill used by them.

I have polluted mine inheritance The Jews, who, as they were his people, were his portion and inheritance, as he was theirs: these he is said to pollute, by suffering the Heathen to enter into the land, and defile their city and sanctuary, and carry them captive into an unclean and idolatrous country.

and given them into your hand to correct and chastise, but in measure, not to kill and destroy.

whereas you showed them no mercy used them very cruelly, and exceeded the commission given.

upon the ancient have you very heavily laid your yoke whose age should have commanded reverence and respect, and whose weakness and infirmities called for compassion; but nothing of this kind was shown; they were not spared because of age, but had insupportable burdens laid upon them; and if not they, then much less young men; see (Lamentations 5:12) .
