'A palace,' as in Psalm 144:12, represents the understanding in which truths have a beautiful form. They have a beautiful form when they are from affection for truth. 'A palace,' as in Amos 4:3, signifies the Word, and consequently, the truth of doctrine which is from good. 'A palace,' as in Isaiah 32:14, signifies the whole church regarding truths from good.
