Matthew Poole and continuators on Job 33:16

16. Then he openeth the ears of men , and sealeth their instruction .

i. e. He revealeth his will to the ears and hearts of men, as this Phrase is used, Iob 36. 10. Psal. 40 6. Isa. 50. 4.

He imprinteth those instructions which he hath revealed to their ears upon their minds, that after they have heard and received them, they do not let them slip, as men commonly do most things which they hear, whether from God or men, but do retain and hold them fast, and are fully satisfied and assured of the truth and importance of them. Or, he sealeth their chastening, or correction, for so this word signifies as well as instruction, i. e. He gives them assurance of his purpose of correcting them for their sins, if they do not prevent it by a speedy repentance. Or, he sealeth it (i. e. his Word conveyed to their Ears and Minds) with chastening them, i. e. He gives them assurance of the truth and reality of his revelation by striking them with a Sacred dread and horror, as was usual in such dreams or night Visions, as we see, Iob 4. 13, 14. Which he did that they might remember it the better, and distinguish this from such vain dreams as are onely the productions of Man's fancy.
