# For in ancient days I broke your yoke; I tore your fetters off you. Still you said, 'I will not serve!'

"Long ago I released you from slavery, but still you refused to worship me!" The people of Israel had been slaves in Egypt. 

# fetters

chains used to restrain a person or an animal

# On every high hill and beneath every leafy tree you lay down as a prostitute

"On every high hill and under every leafy tree you worshiped idols instead of me, like an adulterous wife who is unfaithful to her husband"
