These are comparisons likenesses, parables, symbols, which show the invisible by the visible. Frequently prophets used similitudes to convey the divine meaning to the people, employing such figures as the vineyard (Isa. 5), the image (Dan. 2), the beasts (Dan. 7), the tile and the iron pan (Eze. 4). The LXX for this clause significantly reads, “And by the means of the prophets I was represented.” Similitudes made the prophets’ messages more arresting, easier to understand, and easier to remember. God is here honoring His true prophets by showing that it is only through them that He reveals His will (see Amos 3:7).
