John Gill Commentary Job 26:4

"To whom hast thou uttered words? And whose spirit came forth from thee?" — Job 26:4 (ASV)

To whom have you uttered words ?
&c.] That others know not; do you think you are talking to an ignorant man? Be it known to you, that he knows as much, and can say as much of the Divine Being, of his glories, and of his wondrous ways and works, as yourself, or more:

Or do you consider the circumstances he is in you are speaking to? One under great affliction and distress, to whom it must be unsuitable to talk of the greatness and majesty of God, of his power and strength, of his purity, holiness, and strict justice;

It would have been more proper and pertinent to have discoursed concerning his loving kindness, grace, and mercy, his pity and compassion towards his afflicted people, his readiness to forgive their sins, and overlook their failings; and concerning the promised Redeemer, his righteousness and sacrifice, and of the many instances of divine goodness to the sons of men, and in such like circumstances, by raising them up again, and restoring them to their former happiness.

Some things of this nature would have been more pertinent and suitable, and would have been doing both a wise and friendly part:

and whose spirit came from you ?
Not the spirit of God; do you think yourself inspired by God? Or that what you have said is by the inspiration of his Spirit? Or that you speak like such who are moved by the Holy Ghost? Nor indeed was it his own spirit, or the words and things uttered were not of himself, or flowed not from his own knowledge and understanding of things, but what he had borrowed from Eliphaz; for he had delivered very little more than what Eliphaz had said, (Job 4:17Job 4:18) (Job 15:14Job 15:15) ;

Or else the sense is, whose spirit has been restored, revived, refreshed, and comforted by what you have said? The word of God has such efficacy as to restore the soul, to revive it when drooping, and as it were swooning away and dying, see (Psalms 19:7) (23:3) ; and the words of some good men are spirit and life, the savour of life unto life, and are as life from the dead, very refreshing and comforting; but no such effect followed on what Bildad had said.

Mr. Broughton renders the words, "whose soul admired thee?" You may admire yourself, and your friends may admire you, at least you may think they do, having said in your own opinion admirable things; but who else does? For my own part I do not; and, if saying great and glorious things of God are to any purpose in the controversy between us, I am capable of speaking greater and better things than what have been delivered; and, for instance, let the following be attended to.
