Job 29:23

And they waited for me as for the rain,.... The former rain, as appears by the following clause, which fell in autumn, about October, after seedtime, in order to nourish and cherish it, and bring it up; now as the husbandman waited for this, was in daily expectation of it, and greatly desired it, and longed for it; see James 5:7; so the people waited for Job, for his coming into their public assemblies, whether civil or religious, and longed to hear him speak, for their counsel and instruction, for their comfort and direction in all things they stood in need of:

and they opened their mouth wide [as] for the latter rain; which fell in the spring about March, in the time of harvest, which was of use to fatten the kernals of grain, and make them fuller, and the flour finer; now Job's hearers opened their mouths, as the dry and parched earth gapes for rain; or the husbandman, or the gardener, as the Targum, opens his mouth, and asks and prays for rain; or as a hungry and thirsty man opens his mouth to take in refreshment, or expresses thereby his desire of it; or as persons somewhat deaf open their mouths to hear the better, there being a way through the mouth to the internal ear, as anatomists h observe; which lies through the Eustachian tube, out of the palate, to the internal cavity of the ear, called the "concha"; wherefore such persons naturally open their mouths when they would hear attentively; all which expresses the eager desire of Job's hearers after his doctrine, which, like the rain, would be useful, profitable, and edifying to them; their view was not to indulge their curiosity, to please their ears, but to affect their hearts, and instruct their minds.
