Job 39:30

Her young ones also suck up blood -The word used here (יעלעוּye‛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.
