Albert Barnes' Bible Commentary
Job 39:30
Her young ones also suck up blood - The word used here (יעלעוּ ye‛âl‛û) occurs nowhere else in the Scriptures. It is supposed to mean, to sup up greedily; referring to the fact that the young ones of the eagle devour blood voraciously. They are too feeble to devour the flesh, and hence, they are fed on the blood of the victim. The strength of the eagle consists in the beak, talons, and wings; and such is their power, that they are able to convey animals of considerable size, alive, to their places of abode. They often bear away in this manner, lambs, kids, and the young of the gazelle. Three instances, at least, are known, where they have carried off children. In the year 1737, in Norway, a boy upward of two years of age was carried off by an eagle in the sight of his parents. Anderson, in his history of Iceland, asserts that in that island children of four and five years of age have experienced the same fate; and Ray mentions that in one of the Orkheys an infant of a year old was seized in the talons of an eagle, and conveyed about four miles to its eyry. “Edin. Ency.” The principal food of the young eagle is blood. The proof of this fact may be seen in Scheutzer’s “Phys. Sac., in loc.”
And where the slain are, there is she - Hebrew, “the slain;” referring perhaps primarily to a field of battle - where horses, camels, and human beings, lie in confusion. It is not improbable that the Savior had this passage in view when he said, speaking of the approaching destruction of Jerusalem, “For wheresoever the carcase is, there will the eagles be gathered together; “Matthew 24:28. Of the fact that they thus assemble, there can be no doubt. The “argument” in proof of the wisdom and majesty of the Almighty in these references to the animal creation, is derived from their strength, their instincts, and their special habits. We may make two remarks, in view of the argument as here stated:
(1) One relates to the remarkable accuracy with which they are referred to. The statements are not vague and general, but are minute and characteristic, about the habits and the instincts of the animals referred to. The very things are selected which are now known to distinguish those animals, and which are not found to exist in the same degree, if at all, in others. Subsequent investigations have served to confirm the accuracy of these descriptions, and they may be taken now as a correct account even to the letter of the natural history of the different animals referred to. If, therefore, as has already been stated, this is to be regarded as an indication of the state of natural science in the time of Job. it shows quite an advanced state; if it is not an indication of the existing state of knowledge in his time, if there was no such acquaintance with the animal creation as the result of observation, then it shows that these were truly the words of God, and are to be regarded as direct inspiration. At all events, the statement was evidently made under the influence of inspiration, and is worthy of the origin which it claims.
(2) The second remark is, that the progress of discovery in the science of natural history has only served to confirm and expand the argument here adverted to. Every new fact in regard to the habits and instincts of animals is a new proof of the wisdom and greatness of God and we may appeal now, with all the knowledge which we have on these subjects, with unanswerable force to the habits and instincts of the wild goats of the rock, the wild ass, the rhinoceros, the ostrich, the horse, the hawk, and the eagle, as each one furnishing some striking and special proof of the wisdom, goodness, superintending providence and power of the great Creator.
