Charles H. Spurgeon on Psalms 92:10

If shall be anointed with fresh oil. Montanus has, instead of "fresh oil", given the literal meaning of the original virido oleo, "with green oil." Ainsworth also renders it: "fresh or green oil." The remark of Calmet is: "The plants imparted somewhat of their colour, as well as of their fragrance, hence the expression, `green oil.'"Harmer says, "I shall be anointed with green oil." Some of these writers think the term green, as it is in the original, signifies "precious fragrant oil"; others, literally "green" in colour; and others, "fresh" or newly made oil. But I think it will appear to mean "cold drawn oil", that which has been expressed or squeezed from the nut or fruit without the process of boiling. The Orientals prefer this kind to all others for anointing themselves; it is considered the most precious, the most pure and efficacious. Nearly all their medicinal oils are thus extracted; and because they cannot gain so much by this method as by the boiling process, oils so drawn are very dear. Hence their name for the article thus prepared is also patche, that is, "green oil." But this term, in Eastern phraseology, is applied to other things which are not boiled or raw: thus unboiled water is called patchi-tameer, "green water": patche-pal, likewise, "green milk", means that which has not been boiled, and the butter made from it is called "green butter"; and uncooked meat or yams are known by the same name. I think, therefore, the Psalmist alludes to that valuable article which is called "green oil", on account of its being expressed from the nut or fruit, without the process of boiling. —Joseph Roberts's Oriental Illustrations.
