Olive Trees
This was the principal source of oil in the East, the trees being extensively cultivated on the sides of the hills, and formed into “olive yards.” See OIL. In the temple, within the holy of holies, Solomon made two cherubim of olive wood; the doors into the oracle were also made of the same wood (1 Kings 6:23-3323And within the oracle he made two cherubims of olive tree, each ten cubits high. 24And five cubits was the one wing of the cherub, and five cubits the other wing of the cherub: from the uttermost part of the one wing unto the uttermost part of the other were ten cubits. 25And the other cherub was ten cubits: both the cherubims were of one measure and one size. 26The height of the one cherub was ten cubits, and so was it of the other cherub. 27And he set the cherubims within the inner house: and they stretched forth the wings of the cherubims, so that the wing of the one touched the one wall, and the wing of the other cherub touched the other wall; and their wings touched one another in the midst of the house. 28And he overlaid the cherubims with gold. 29And he carved all the walls of the house round about with carved figures of cherubims and palm trees and open flowers, within and without. 30And the floor of the house he overlaid with gold, within and without. 31And for the entering of the oracle he made doors of olive tree: the lintel and side posts were a fifth part of the wall. 32The two doors also were of olive tree; and he carved upon them carvings of cherubims and palm trees and open flowers, and overlaid them with gold, and spread gold upon the cherubims, and upon the palm trees. 33So also made he for the door of the temple posts of olive tree, a fourth part of the wall. (1 Kings 6:23‑33)).
Israel in general is called a green olive tree, fair and of goodly fruit (Jer. 11:1616The Lord called thy name, A green olive tree, fair, and of goodly fruit: with the noise of a great tumult he hath kindled fire upon it, and the branches of it are broken. (Jeremiah 11:16)); and a good olive tree, with root and fatness; in contrast to the Gentiles who are compared to a wild olive tree. The fact that the wild olive tree needs grafting gives point to the passage in Romans 11:17-2417And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree; 18Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee. 19Thou wilt say then, The branches were broken off, that I might be graffed in. 20Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: 21For if God spared not the natural branches, take heed lest he also spare not thee. 22Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off. 23And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again. 24For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree? (Romans 11:17‑24). God’s two Jewish witnesses in a future day are called the two olive trees and the two candlesticks standing before the God of the earth. They will then be the fruit and light bearers on the earth (Zech. 4:3,11,143And two olive trees by it, one upon the right side of the bowl, and the other upon the left side thereof. (Zechariah 4:3)
11Then answered I, and said unto him, What are these two olive trees upon the right side of the candlestick and upon the left side thereof? (Zechariah 4:11)
14Then said he, These are the two anointed ones, that stand by the Lord of the whole earth. (Zechariah 4:14)
; Rev. 11:3-43And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. 4These are the two olive trees, and the two candlesticks standing before the God of the earth. (Revelation 11:3‑4)). The Hebrew is zayith, and the Arabic name is zeitun; it is the Olea Europæa.
