Job 12:3 - Matthew Poole's English Annotations on the Holy Bible

An understanding, Heb. a heart; which is oft put for the understanding, as Job 34:34 Jeremiah 5:21 Acts 8:22; i.e. God hath given me also the knowledge and ability to judge of these matters. I am not inferior to you in these things; which he speaketh, not in a way of vain-glorious boasting, but for the just and necessary vindication both of himself; and of that cause of God, which for the matter and substance of it he maintained rightly, as God himself attests, Job 42:7. Who knoweth not such things as these? the truth is, neither you nor I have any reason to be puffed up with our knowledge of these things; for the most foolish and barbarous nations know that God is infinite in wisdom, and power, and justice. But this is not the question between you and me.
