Such a wholesale slaughter of all the prophets goes without parallel in scriptural history. It also marks a great turning point of the Jaredite society. Previously, the kings had protected them, And it came to pass that king Shule did execute judgment against all those who did revile against the prophets (Ether 7:24-25). In the same manner, Com provided protection (v. 2). But the days of Shiblom and his brother brought drastic change.
There are layers of rebellion against the Lord’s prophets. The first layers are indifference and criticism which naturally lead to rejection and mockery. But the final stage is open persecution and murder. The Lord takes the rejection of his prophets personally, for he has said he that receiveth my servants receiveth me (DC 84:36), but the converse is also true, he that rejects his servants rejects Him—whether by mine own voice or by the voice of my servants, it is the same (DC 1:38). Accordingly, the Lord has promised his servants, saying whoso rejecteth you shall be rejected of my Father and his house (DC 99:4). Wo…unto that house, or that village or city that rejecteth you, or your words, or your testimony of me; For I, the Almighty, have laid my hands upon the nations, to scourge them for their wickedness (DC 84:95-96). The Jaredites were ripe for just such a scourge.
