Job 9:4

“[He is] wise in heart, etc.] Originally, essentially, truly, really, and perfectly so; he is the only, and the all wise God; his understanding is infinite; he is able to traverse all the schemes of men, in things civil or religious, and disappoint all their devices; for though there be ever so many of them, or be ever so deeply laid, the counsel of the Lord, that shall stand; for there is no wisdom, understanding, or counsel against him; and therefore it is in vain to contend with him: he is so wise and knowing, that he sees and knows all that is in man, or is done by him, whether in public or in private; there is not a thought in his heart, nor a word on his tongue, nor an action in his…”
