Allegory of the salt without savour

Matt 5:13 [1], [2] Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men. Luke 14:34 [3] Salt is good: but if the salt have lost his savour, wherewith shall it be seasoned? 35 It is neither fit for the land, nor yet for the dunghill; but men cast it out. He that hath ears to hear, let him hear [4].

[1]At this point the two speeches diverge entirely. Giving the gospels the benefit of the doubt, I have placed the remainder of the speeches one after the other on the assumption that they are parts of the same speech.

[2]Compare this sentence and the sentence from Luke which parallels it with Mark 9:50.

[3]This section from Luke is taken from one of Jesus' many "speeches to the multitude." In the original, it does not actually follow the piece which I have placed before it, but has been put here for the sake of comparison.

[4]The phrase meaning (or one similar to) "He that hath ears to hear, let him hear," also appears in Mark 4:9, 4:23, 7:16, Matthew 11:15, 13:9, 13:43, and Luke 8:8. It does not appear in John.
