Proverbs 15:33

33 The fear of Jahve is a discipline to wisdom, And before honour is humility. We may regard 'יראת ה (the fear of Jahve) also as pred. here. The fear of Jahve is an educational maxim, and the end of education of the Chokma; but the phrase may also be the subject, and by such a rendering Luther's parallelism lies nearer: "The fear of the Lord is discipline to wisdom;" the fear of God, viz., continually exercised and tried, is the right school of wisdom, and humility is the right way to honour. Similar is the connection מוּסר השׂכּל, discipline binds understanding to itself as its consequence, Pro 1:3. Line second repeats itself, Pro 18:12, "Pride comes before the fall." Luther's "And ere one comes to honour, he must previously suffer," renders עני rather than ענוה. But the Syr. reverses the idea: the honour of the humble goeth before him, as also one of the anonymous Greek versions: προπορεύεται δὲ ταπεινοῖς δόξα. But the δόξα comes, as the above proverb expresses it, afterwards. The way to the height lies through the depth, the depth of humility under the hand of God, and, as ענוה expresses, of self-humiliation.

See here how much it is our interest, as well as duty, 1. To submit to our God, and keep up a reverence for him: The fear of the Lord, as it is the beginning of wisdom, so it is the instruction and correction of wisdom; the principles of religion, closely adhered to, will improve our knowledge, rectify our mistakes, and be the best and surest guide of our way. An awe of God upon our spirits will put us upon the wisest counsels and chastise us when we say or do unwisely. 2. To stoop to our brethren, and keep up a respect for them. Where there is humility there is a happy presage of honour and preparative for it. Those that humble themselves shall be exalted here and hereafter.

15:33 Fear of the Lord fosters humility because proper regard for God counteracts our delusions of self-sufficiency.
