Biblical exegesis is a wonderful God-given skill. It enables the exegete to draw out of Scripture the meaning intended by the Holy Spirit, as opposed to imposing on Scripture a meaning that the reader has already determined (eisegesis is reading into Scripture one’s own prejudices).
There are many principles for exegesis, but one of them is to be aware of biblical metaphors.
The failure to notice that ‘Woe to them that are at ease in Zion’ Amo 6:1 is a metaphor, applied to the careless in Samaria, has led some exegetes to think that Amos is addressing those living in Zion in Jerusalem.
Just as we apply this phrase to people of our acquaintance, so it appears that it was already a metaphor in Old Testament times.
