Isaiah 1:2-3

God Himself charged the Israelites with their sin. He called the heavens and earth to witness His indictment against His people (cf. Deuteronomy 30:19; Deuteronomy 32:1). His people had not only violated His covenant but common decency and good sense. Isaiah’s references to the Mosaic Covenant were less explicit than Jeremiah’s were, though both men viewed the covenant as the basis of Israelite life.

It was unthinkable that children should revolt against a loving father who nurtured them. Even stupid oxen and donkeys know their master, but the Israelites did not realize who cared for them. The Israelites made animals look intelligent.
