He takes away the speech of the trustworthy, and takes away the understanding of the aged.

23. When the priest does not do the good that he tells, even the very word of his lips is withdrawn from him, that he may not dare to speak what he does not practise; as where it is said by the Prophet, But unto the wicked God saith, ‘What hast thou to do, to declare My statutes, or that thou takest My covenant in thy mouth? [Ps. 50, 16] Whence also he beseeches, saying, And take not the word of truth utterly out of my mouth. [Ps. 119, 43] For he reflects that Almighty God gives the word of truth to those that do it, and takes it away from those that do it not. He then that prayed that he might not have it ‘taken out of his mouth,’ what did he else than pray for the grace of good practice? As if he said in plain words, ‘Let me not go astray from good works, lest, while I lose the regularity of good living, I also part with the right rule of speaking.’ And for the most part the teacher, who ventures to teach what he neglects to practise, when he ceases to speak the good which he scorned to do, begins to teach his charge the evil things that he does, that, by the righteous judgment of the Almighty, that man may not henceforth have a tongue for a good theme, who will not have a good life; so that whilst his mind is inflamed with the love of earthly things, he should be ever speaking of earthly things. Whence ‘Truth’ saith in the Gospel, For out of the abundance of the heart the mouth speaketh. A good man out of the good treasure of the heart bringeth forth good things, and an evil man out of the evil treasure bringeth forth evil things. [Matt. 12, 34. 35.] Hence also John saith, They are of the world, therefore speak they of the world. [1John 4, 5] Therefore it is well said, Who changeth the lip of the truthful, and taketh away the instruction of the aged. In that while they, who were aforetime ‘truthful’ in preaching heavenly things, setting their affections on those of time, are sunk down to the same, ‘the lip of the truthful is changed, and the instruction of the aged taken away;’ in that being in love with temporal things, they never follow the precepts of their predecessors, so as to be occupying the place of authority as if but for the fruit of pleasure, and for no good end of labour.
24. Which nevertheless may be understood more plainly of the Jews, who before the Lord’s Incarnation were ‘truthful,’ in that they believed that He was to come, and proclaimed the same; but when He appeared in the flesh, they denied that it was He. Therefore ‘the lip of the truthful was changed,’ in that Him, of Whom they had told that He was about to come, they denied when present; ‘and the instruction of the aged was taken away,’ in that they never followed in believing the things, which they remembered their fathers to have foretold. Whence too at the coming of Elijah it is promised, that he shall ‘turn the hearts of the children to their fathers;’ that ‘the instruction of the aged,’ which is now ‘taken away’ from the heart of the Jews, upon the Lord taking compassion on them, may then be brought back, when the children begin to understand that concerning the Lord, which their fathers foretold. But if by ‘the aged’ we understand likewise those same Jews, who, by the persuasions of unbelief, set themselves to oppose the word of ‘Truth,’ then ‘the instruction of the aged was taken away,’ when the Church consisting of the Gentiles, being indeed young, received it, as she saith by the Psalmist, I understand more than the ancients. [Ps. 119, 100] And because she kept this same in practising it, in what way she came to understand more than the ancients, she makes plain, whereas she adds directly, Because I keep thy precepts. For whereas she aimed to fulfil in practising that thing which she learnt, it was vouchsafed her to understand what she might teach.
