Zechariah 4:3

4:3 There are also two olive trees beside it, one on the right of the receptacle and the other on the left.”

Zechariah 4:11-14

4:11 Next I asked the messenger, “What are these two olive trees on the right and the left of the menorah?” 4:12 Before he could reply I asked again, “What are these two extensions of the olive trees, which are emptying out the golden oil through the two golden pipes?” 4:13 He replied, “Don’t you know what these are?” And I said, “No, sir.” 4:14 So he said, “These are the two anointed ones who stand by the Lord of the whole earth.”
