O radix Jesse, qui stas in signum populórum, super quem continébunt reges os suum, quem Gentes deprecabúntur : veni ad liberándum nos, jam noli tardáre.
O Root of Jesse, Who standest as a sign of the people, towards Whom the kings hold their tongues, Whom the Gentiles shall implore : Come for to deliver us, now do not delay!
There are people who believe that others should hang on their every word. This is a particular vice of teachers (mea culpa) and professors. If they have the authority to speak, then all well and good; their words can be understood and received confidently with that authority. However, there are some who speak on matter on which they are not qualified and make pronouncements that destroy rather than build up. There are those who seek to undermine peoples' faith with their own "discoveries" and "interpretations".
The Root of Jesse will always stand as a signpost to the Truth and against delusion, particularly self-delusion. If one argues against that Root, the Root is withdrawn from them and they have no basis on which to build their conclusion. It is far better to have the humility to say "actually, I don't know" and submit oneself to the diligent and careful unearthing of the Root rather than to make a noise like sounding brass, or a tinkling cymbal.
