Job 27:11

I will teach you by the hand of God: [that] which [is] with the Almighty will I not conceal.

Ver. 11. I will teach you by the hand of God] That is, by the help of God, συν Yεω, or concerning the hand of God, what is in the hand of the Lord (so the Septuagint), what things he is wont to do by his power, and what are his usual proceedings, his actual and efficacious providence, Acts 4:28. Deo iuvante et subministrante facultates (Vat.).

That which is with the Almighty I will not conceal] Neque celabo, ut res divinae comparatae sint, so the Tigurines translate. Envious masters use to hide from their scholars the best and chiefest part of their skill. It is reported of that spotted beast, the lynx, that knowing that his urine will congeal into a precious stone, and so stand man in stead, of pure envy, when he pisseth he maketh a hole in the ground to cover it. Cardan, speaking of one that had a receipt that would suddenly and certainly dissolve a stone in the bladder, and died, not imparting his skill to any one, I doubt not, saith he, but that man went to hell, quod moriens, artem suam mortalibus inviserit, because he envied his skill to those that survived him. Job was none such: but what he knew of God's mind and manner of dealing (which hath no certain law, nor invariable rule, but dependeth upon his mere pleasure) he was ready to impart to his friends, who measured God's actions by a wrong rule.
