Commentators unanimously agree that Israel's core sin was attributing God's blessings to false sources. She received necessities like bread and water and luxuries like oil and fine fabrics, but credited her 'lovers' (idols) for them. This profound ingratitude is a central theme. One scholar suggests a modern parallel is when people thank 'Nature,' 'Fortune,' or 'the universe' for their blessings instead of acknowledging the true Giver, God Himself.
