Job 21:24

His breasts are full of milk Perhaps, his vessels are full of milk; but the meaning is uncertain, the word rendered "breasts" not occurring again. The word however has analogies in the cognate languages, and may mean vessels, or troughs, marg. milk-pails, the reference being to the plenty and richness of the man's herds and possessions, though this is a figure for plenty in general. By a slight alteration in spelling the word "milk" means fat, and the ancient versions so read, translating, his inwards, or sides, are full of fat.

his bones are moistened with marrow Rather, and the marrow of his bones is moistened, lit. watered, i. e. made fresh and strong. If the first clause be translated with the ancient Versions this clause is parallel in sense; otherwise, it describes the effect of his plenty on the man himself.
